Fused Silica Powder

Descripción del producto

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 thermo conductivity. Our fused silica is mainly used in the fields of epoxy molding compound, casting, refractory, precision ceramics and casting, shell mould, silicon rubber, electrical insulator and poly-silicon ingot industries etc.
