Difference between quartz, fused silica and Borofloat glass?

In summary, quartz, fused silica, and Borofloat glass are all types of glass materials with some similarities but also distinct differences. Quartz is a hard mineral composed of silicon dioxide and is commonly used in electronics and optics. Fused silica is a type of glass made from pure silica using high temperature fusion processes, resulting in a higher purity and better optical properties. Borofloat glass is a specialty glass made from a boron oxide and silicon dioxide composition, known for its high thermal shock resistance and low thermal expansion. The main differences between these types of glass lie in their chemical compositions and manufacturing processes, with each type having its own unique properties suitable for different applications.

I am looking over the supplies on University Wafer until I notice the following:
link: https://order.universitywafer.com/default.aspx?cat=Borofloat 33 Glass&diam=100mm

They sell quartz, fused silica and Borofloat glass as different products. I thought quartz and fused silica are the same? Is there anyone that can in details explain the difference between three products?

FAQ: Difference between quartz, fused silica and Borofloat glass?

What is the difference between quartz, fused silica, and Borofloat glass?

Quartz, fused silica, and Borofloat glass are all types of glass materials. They have some similarities but also some distinct differences.

What is quartz?

Quartz is a mineral composed of silicon dioxide (SiO2). It is a hard, crystalline material that is often used in electronics, optics, and other applications due to its high thermal and chemical resistance.

What is fused silica?

Fused silica is a type of glass made from pure silica (SiO2) using high temperature fusion processes. It has a similar chemical composition to quartz but is manufactured in a different way, resulting in a higher purity and better optical properties.

What is Borofloat glass?

Borofloat glass is a specialty glass made from a boron oxide (B2O3) and silicon dioxide (SiO2) composition. It is known for its high thermal shock resistance and low thermal expansion, making it suitable for use in high-temperature applications.

What are the main differences between these types of glass?

The main differences between quartz, fused silica, and Borofloat glass lie in their chemical compositions and manufacturing processes. Quartz and fused silica have similar chemical compositions, but fused silica is purer and has better optical properties. Borofloat glass has a different chemical composition and is known for its high thermal shock resistance and low thermal expansion. Each type of glass has its own unique properties and is suitable for different applications.
