Fused silica is manufactured from high purity natural silica stone, melted at extremely temperature. Then cooling, crashing, grinding into lump as usage. With high purity, high chemical and electricity resistance, lowest thermal expansion and exceptionally good thermal shock resistance and lower thermoconductivity. Our fused silica is mainly used in the fields of epoxy molding compound, casting, refractory, precision ceramics, crucible and casting, shell mould, silicon rubber, electrical insulator and marble industries etc.
