Fused Silica properties include good thermal shock resistance, a thermal expansion coefficient close to zero and excellent mechanical properties at high temperatures, making Fused Silica refractory components particularly useful for very demanding applications. Additional properties include chemical stability and low electrical conductivity; although it should be noted that due to its physical structure use at temperatures exceeding 1000ºC is not possible for cyclic applications. Despite this, the material performs well in the refractory environment, often being used in components such as firing supports, ignition crucibles ancell nameishes.
