Fused Silica Properties

· glass,quartz,fused silica

Fused Silica, which is also called as synthetic quartz is made by melting crystalline silica sand. It forms high purity transparent glass and nearly 100 percent pure silicon dioxide. It has a low coefficient of thermal expansion and high viscosity, that's why it has various applications over other glass.


Fused Silica is known for its

  • Resistance to high Temperature.
  • Low Coefficient of thermal expansion.
  • High Corrosion Resistance
  • Extreme hard
  • Permeability
  • High Chemical Purity
  • High Optical Transmission Power
  • Low birefringence value
  • Highly Electrical Insulation
  • Low birefringence Value.
  • It is hard and brittle, their machinability is relatively good.
  • Low dielectric loss.
  • It can be polished and lapped to fine finishes.
