Company name: Lianyungang Chemsize International Trading Co., Ltd.
Fused silica is a high purity quartz sand that has been melted to form glass. Its high volume stability, low volumetric expansion, and high purity make it a versatile material for refractory applications.
At Lianyungang Chemsize International Trading Co., Ltd., we carefully select high purity silica sand (SiO2 > 99%) from Donghai/Xinyi as our raw material. The silica sand is melted at temperatures ranging from 2000-2300 ºC to form amorphous silicon dioxide glassy ingots, which are then processed into fused silica lumps, sand, and powder according to customer specifications.

Explore our High Performance Fused Silica Flour for top-grade quartz materials. Trust the leading silica powder supplier for premium quality.
Fused Silica is produced from high purity crystal silica sourced from China Donghai-Xinyi. It is electrically fused at temperatures ranging from 1800-2000ºC to create amorphous Silicon dioxide. The material is then engineered into various forms such as lumps, cullet, ingots, sand, grain, granular, and powder flour. These forms are specifically designed for manufacturing PV fused silica crucibles, thermal ceramics, refractories, EMC investment casting ceramic shells, and more.
