Fused Silica

 

 

Fused silica is a compound of silicon and oxygen. For dielectric applications, silicates are modified with magnesium and/or aluminum to provide sufficient dielectric properties. Cordierite and steatite are silicate commonly used in dielectric applications. High purity amorphous fused silica is a high performance ceramic with very low expansion, remarkable thermal shock resistance, low thermal conductivity, excellent electrical insulation up to 1000°C and excellent resistance to corrosion from molten metal and glass.
