Silica Glass SiO2
Description
Fused Silica is the glassy form of Quartz and is thus isotropic. Fused Silica is tough and hard and has a very low expansion. Normal varieties of Fused Silica contain water which gives strong absorption in the Infra-red. Water-free varieties of Fused Silica are available.
