Product Description

Product Description

 

Material for refractory slurry. Specially for investment casting, producing of ceramic moulds. 
Fused quartz is made of refined quartz sand after melting at high temperature, cooling, crushing and grading of the block and processing it into various specifications of particles according to the use. It has high SiO2 content, close to zero thermal expansion coefficient, good electrical insulation, heat resistance and very low heat conductivity. Its mainly used in epoxy sealant, precision casting, refractory, fine ceramics, casting mold, silicone rubber, marble and other industries.
