High Grade Cristobalite

Product Overview

Description

Crystalline silica powder is produced from white natural quartz stone through the processing of manual selection, ex-ior water dispose, fine grinding, filtrating, drying and sieving etc. With high purity and white colour which has stable physical and chemical properties and controllable particle size distribution, is widely used as material for epoxy potting compound, epoxy mould compound of electronic and electrical appliance industry. As well as engineering plastics, silicon rubber, precision ceramics and casting, painting etc.
