Fused Silica Powder

SiO2, Amorphous



Fused Silica is a high purity grade of silica, which is around 99.4-99.9% SiO2. Fused Silica is produced by carbon arc, plasma arc, gas fired continual extrusion or carbon electrode fusion. Fused Silica is primarily used in the electronics industry (around 70% of the total market) where its good dielectric and insulating properties are exploited; though it may also be used as a refractory material or in investment casting.

Fused silica is used in the refractory casting slurry, where it coats a wax replica of the component to be cast. The refractory stucco is fired and molten metal is poured into the mould. Finally, the fused silica shell is knocked out. Fused silica makes this knock out stage easier than other refractories such as zirconia and aluminosilicates.
