Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion (≈3 × 10−6 K−1 at 20 °C), making them more resistant to thermal shock than any other common glass. Such glass is subjected to less thermal stress and can withstand temperature differentials without fracturing of about 165 °C (300 °F). It is commonly used for the construction of reagent bottles and flasks, as well as lighting, electronics, and cookware. Borosilicate glass melts at about 1,650 °C (3,000 °F; 1,920 K).
Benefits of Borosilicate Glass
Optical Clarity
Compared to the array of plastics, metals and other materials of construction, borosilicate glass provides a smooth surface that offers an unobstructed view of what is going on inside the equipment, enhancing the level of observation in any process.
Cleanability
Some materials of construction can pose housekeeping issues when it comes to ease of cleaning. The anti-stick, nonporous surface makes borosilicate glass a popular choice for compliant applications. And its transparency allows you to see when equipment needs to be cleaned without the need for interrupting the process and performing an internal inspection.
Compact Design
Compared to systems built using alternative materials of construction, borosilicate glass components are much more compact making a borosilicate glass system significantly smaller. This is especially beneficial in facilities that are facing space constraints as well as work areas where headroom can become an issue. The compact arrangement can also make shipping, delivery, and installation easier.
Corrosion Resistance
Similar to the properties of glass-lined steel, borosilicate glass equipment provides unsurpassed corrosion resistance to water, neutral and acidic solutions, concentrated acids and acid mixtures, and to chlorine, bromine, iodine and organic substances. Its resistance to chemical attack is superior to that of most metals and other materials, even during prolonged periods of exposure and at temperatures above 100 °C. There are only a few chemicals which can cause noticeable corrosion of the borosilicate glass surface - hydrofluoric acid, concentrated phosphoric acid and strong caustic solutions at elevated temperatures. However, at ambient temperatures caustic solutions up to 30% concentration can be handled by borosilicate glass without difficulty.
Temperature Range
Borosilicate glass' strong resistance to temperature makes it desirable in chemical and pharmaceutical processes. The maximum permissible operating temperature for QVF borosilicate glass is 200°C (due to limiting factors such as PTFE gaskets). Above a temperature of 525°C the glass begins to soften and above a temperature of 860°C it changes to the liquid state. Conversely, it can be cooled down to the maximum possible negative temperature, but is generally recommended for use down to – 80°C. An additional benefit within temperature allowance is the ability for borosilicate glass to be exposed to two different temperatures at the same time (though for safety reasons it is recommended that temperature difference does not exceed 100 K).
Structural Integrity Due to Low Thermal Expansion
Directly related to the large temperature differential comes the benefit of low thermal expansion. Because borosilicate glass doesn't expand like ordinary glass, there is a smoother transition between temperatures as well as the ability to withstand different temperatures at the same time. Borosilicate glass has an extremely low coefficient of linear expansion (3.3 x 10–6 K–1) as a result of its low thermal expansion. Additionally, the low thermal expansion coefficient eliminates the need for expensive measures to compensate for thermal expansion resulting from changes in temperature. This becomes especially significant in the layout of long runs of glass pipeline, ensuring a high level of structural integrity. For this reason, borosilicate glass is an approved and proven material in the construction of pressure equipment.
Affordability
Compared to other materials of construction that offer similar properties such as corrosion resistance, borosilicate glass is relatively economical to produce. When compared to the other options such as quartz, borosilicate glass is an extremely affordable solution. Its sustainability is an additional factor that adds to its affordability; with proper maintenance and care, your borosilicate glass equipment can have a long life.
Inert Behavior
Because there is no interaction or ion exchange between the process media and glass, there is no catalytic effect. The inertness of borosilicate glass also means it is nonflammable and poses no environmental risk. Due to the inert behavior of borosilicate glass, there is no smell or taste alterations and can therefore be used in an almost unrestricted way in pharmaceutical applications and in the food and beverage industry.
Uses of Borosilicate Glass
Health and Science
Virtually all modern laboratory glassware is made of borosilicate glass. It is widely used in this application due to its chemical and thermal resistance and good optical clarity, but the glass can react with sodium hydride upon heating to produce sodium borohydride, a common laboratory reducing agent. Fused quartz is also found in some laboratory equipment when its higher melting point and transmission of UV are required (e.g. for tube furnace liners and UV cuvettes), but the cost and manufacturing difficulties associated with fused quartz make it an impractical investment for the majority of laboratory equipment. Additionally, borosilicate glass is used as the feedstock for the production of parenteral drug packaging, such as vials and pre-filled syringes, as well as ampoules and dental cartridges. The chemical resistance of borosilicate glass minimizes the migration of sodium ions from the glass matrix, thus making it well suited for injectable-drug applications.
Electronics
During the mid-20th century, borosilicate glass was used to pipe coolants (often distilled water) through high-power vacuum-tube–based electronic equipment, such as commercial broadcast transmitters. It was also used for the envelope material for glass transmitting tubes which operated at high temperatures. Borosilicate glasses also have an application in the semiconductor industry in the development of microelectromechanical systems (MEMS), as part of stacks of etched silicon wafers bonded to the etched borosilicate glass.
Cookware
Cookware is another common usage for borosilicate glass, including bakeware. It is used for some measuring cups, featuring screen printed markings providing graduated measurements. Borosilicate glass is sometimes used for high-quality beverage glassware, particularly in pieces designed for hot drinks. Items made of borosilicate glass can be thin yet durable, or thicker for extra strength, and are microwave- and dishwasher-safe.
Lighting
Many high-quality flashlights use borosilicate glass for the lens. This increases light transmittance through the lens compared to plastics and lower-quality glass. Several types of high-intensity discharge (HID) lamps, such as mercury-vapor and metal-halide lamps, use borosilicate glass as the outer envelope material.
Optics
Many astronomical reflecting telescopes use glass mirror components made of borosilicate glass because of its low coefficient of thermal expansion. This makes very precise optical surfaces possible that change very little with temperature, and matched glass mirror components that "track" across temperature changes and retain the optical system's characteristics.
Rapid Prototyping
Borosilicate glass has become the material of choice for fused deposition modeling (FDM), or fused filament fabrication (FFF), build plates. Its low coefficient of expansion makes borosilicate glass, when used in combination with resistance-heating plates and pads, an ideal material for the heated build platform onto which plastic materials are extruded one layer at a time.
Key Factors to Consider When Choosing Borosilicate Glass for Your Application
Temperature Range
If your application involves exposure to extreme temperatures, it is important to choose borosilicate glass that is rated to withstand those temperatures. The glass should be able to withstand the maximum and minimum temperatures it will be exposed to without breaking or shattering.
Chemical Resistance
If your application involves exposure to chemicals, it is important to choose borosilicate glass that is resistant to those chemicals. You should consider the pH range and specific chemicals that the glass will be exposed to in order to choose a glass that is suitable for your application.
Mechanical Strength
The mechanical strength of the borosilicate glass should be considered if your application involves the glass being subjected to stress or impact. You should choose a glass with a high level of mechanical strength in order to ensure it can withstand the forces it will be subjected to.
Optical Clarity
If your application requires good visibility through the glass, it is important to choose a borosilicate glass with good optical clarity. This will ensure that you can see through the glass clearly without any distortions or distortions.
Size and Shape
You should also consider the size and shape of the borosilicate glass that is appropriate for your application. The glass should be able to fit into the required space and have the appropriate shape for your needs.
How to Maintain Borosilicate Glass
Inspect Before Use
Do always inspect your borosilicate glass before use. Even new glass can be damaged in transit, and previously-damaged glass can be bumped during cleaning or storage. The quick and easy way to check if a glass is damaged is to hold it up to sunlight: if you see small fractures or star-shaped cracks, then the glass is damaged.
Washing & Cleaning
Thorough Rinse After Every Use
After using, rinse the borosilicate glass vessel thoroughly with warm water. This helps prevent the accumulation of residue and maintains the glass's pristine appearance.
Handle with Care
Don't bump your borosilicate glass against a sink wall or against other vessels during cleaning. You could damage the vessel, even subtly, and progressive damage reduces the life of the vessel and introduces safety hazards.
Choose Right Cleaner
Don't use hydrofluoric acid or strong alkali soaps or acids to clean borosilicate glassware. Hydrofluoric acid is highly corrosive to borosilicate glass, and strong alkali soaps / acids are also damaging.
Gentle Cleaning Techniques
Borosilicate glass is sturdy but can be scratched by abrasive materials. Opt for a soft sponge or cloth to clean the exterior and interior. For stubborn stains, a mixture of warm water and mild dish soap should do the trick.
Use a Bottle Brush for Deep Cleaning
For those hard-to-reach spots, invest in a bottle brush with soft bristles. This ensures a thorough cleaning of the inside, reaching every nook and cranny without causing damage.
Avoid Freezing or Boiling Liquids
While borosilicate glass is resistant to thermal shock, extreme temperatures can still pose a risk. Avoid freezing or boiling liquids directly in the vessel to prevent stress on the glass.
Eco-Friendly Drying
After washing, let your borosilicate glass air-dry or use a soft cloth. Avoid using paper towels or harsh materials that could scratch the surface. Do triple-check borosilicate glassware for damage before subjecting it to heating or autoclaving. Even tiny cracks and abrasions can cause glassware to fail under high temperatures and pressures.
Mindful Storage
When not in use, store your borosilicate glass in a safe place, away from heavy items or crowded spaces. This prevents accidental knocks or falls that could lead to breakage.
Regular Inspections
Give your glass regular inspections to check for any signs of wear, chips, or cracks. If you notice any damage, it's best to retire the glass for safety reasons.
