Fused Silica – Sibelco

Introduction. Fused silica is an angular “shaped” silica produced by grinding and milling high purity silica/quartz. Fused silica therefore has the same intrinsic properties as any other silica. Its chemical formula is SiO2. At Sibelco high purity quartz is being used to make fused silica. Quartz (silica, SiO2) is the core mineral within ...
