Question

What is difference between quartz and quartz glass ?

Answer 1

They both work well as high temperature view ports, optical windows, and in areas that require good chemical resistance. The maindifference between the two is that Fused Silica is composed of a non-crystalline silica glass, while Quartz is made from crystalline silica.

Answer 2

The main difference between the two is that Fused Silica is composed of a non-crystalline silica glass, while Quartz is made from crystalline silica. This difference gives Fused Silica very high transmission in the UV spectrum compared to that of Quartz.
