Fused silica powder

Fused silica powder, also known as fused silica powder, fused quartz powder (Fused silica) Lianyungang wohua new material technology companies to use the high quality natural quartz Donghai County, by high temperature melting, after cooling the amorphous silica as the main raw material, quartz powder by Lianyungang Wo Huaxin materials science and technology company's unique processing of the.

Fused silica powder (fused silica powder) has high purity, small thermal expansion coefficient, low internal stress, high humidity resistance and low radioactivity. And has the following characteristics: very low coefficient of linear expansion; good electromagnetic radiation; chemical resistance and other stable chemical characteristics; reasonable, orderly and controllable particle size distribution.

This product is mainly used in electronic packaging, investment casting, high-grade electrical insulation, paint, coating, silicone rubber and other industries. Main technical performance indexes of fused silica powder.
