Fused Silica
Fused Silica has an extremely low thermal expansion and a low thermal conductivity, therefore it is an excellent refractory raw material for the glass industry and for steel continues casting refractories. Fused Silica is produced by fusing natural high purity quartz sand in electric arc furnaces
