Seriese of Fused quartzproducts

Fused silica ismanufactured from high purity natural silica stone, melted atextremely temperature .then cooling ,crashing , grinding into lumpas usage.  With high purity, high chemical and electricityresistance, lowest thermal expansion  and exceptionally goodthermal shock resistance and lower thermoconductivity. Our fusedsilica is mainly used in the fields of epoxy molding compound,casting, refractory, precision ceramics ,crucible and casting,shell mould, silicon rubber, electrical insulator and marbleindustries etc.
