Physical Properties of Fused Silica

• Density: 2.2 g/cm3
• Coefficient of Thermal Expansion: 5.8*10^-7 /k (298 ~ 573 deg K)
• Thermochromism: Under constant temperature of 1140 degrees, keep annealing for 30 minutes without discoloration.
  

Fused silica (SiO2) wafers are made from high purity fused silica, ground and polished to optical grade on both sides. The fused silica wafers are suitable for many optical applications because of their excellent optical transmission characteristics. Fused silica also has excellent chemical resistance against a wide variety of solvents, as well as exceptional heat resistance, with high dimensional stability over a wide temperature range thanks to its ultra low thermal expansion coefficient.

Single Crystal Quartz Wafers and Substrates are also available.
