Should you Choose Quartz or Borosilicate Glass in Custom Glass Products?
Debating quartz vs borosilicate glass in your custom glass component? Choosing the right glass makes or breaks the success of a custom manufactured glass component.
Consider the many variables to select the right material for glass fabrication. These include cost, temperature resistance, and versatility. Two popular choices are quartz and borosilicate glass, each with its own strengths and advantages depending on the application.
Both quartz and borosilicate glass are versatile materials. Similarly, they are manipulated into many shapes and sizes using techniques such as shrinking, grinding, polishing and formed using a lathe or bench burner. Both types of glass are used in glass-to-glass seals. The following advantages and applications exist in both types of glass:
Borosilicate Glass Attributes
Borosilicate glass is much easier to hot-work than quartz glass, making it a lower cost option for glass fabrication. Because it is an engineered material, borosilicate glass comes in different chemical compositions for use in applications where conditions may be too harsh for a standard household glass.
Stock size options of borosilicate 33 COE meet specific sizing or geometric needs. In addition, some varieties of borosilicate glass can also be sealed directly to metal, such as Kovar (8447, 8250 and 8245) and tungsten (8487). It is easily moldable when compared to quartz glass. Depending on the unique need for a project, there is a wide variety of types of borosilicate glass to suit specific applications, often including:
- Laser components
- Reduction tubes
- Spray chambers
- Dye cells
- Hollow cathode lamp bodies
- Water jackets
- Sight glass tubes
- Plasma tubes
- Parenteral drug packaging, such as vials, pre-filled syringes, and ampules
- X-ray components used in baggage scanning, fuel scanning, and medical devices
Quartz Glass Attributes
More expensive than borosilicate glass, quartz glass has a different forming process. It is ideal for a variety of configurations ranging from natural to synthetic. Similarly, like borosilicate glass, quartz glass meets specific sizing or geometric needs when modified.
However, quartz allows tailoring of its properties for optimal performance in applications. Quartz adjusts for different transmission curves. As a result, this allows or blocks certain wavelengths. Above all, quartz is a versatile glass. It is melted, bent, fused, drawn, and welded into tube and rod forms. Consequently, other characteristics of quartz glass include low thermal expansion with high resistance to thermal shocks, high UV and infrared transparency, and high radiation resistance.
Some typical applications for quartz glass include fabricating components for:
- UV transmission and high-temperature applications
- Semiconductor and photovoltaic manufacturing
- Optical fibers and optical materials for all sorts of applications
- ICP and OES consumables
- Water Purification Components
- Light pipes
