Mineral: Fused Silica
In APAC, Sibelco’s Fused Silica is used in high voltage insulators.
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.
Production Location: Yeonmu, Korea
Application: Reinforcement and dimensional stability (low shrinkage) – good electrical insulating
