Company Name: Lianyungang Chemsize International Trading Co., Ltd.
Fused silica is high purity quartz sand that has been melted to form glass. Its high volume stability, low volumetric expansion, and high purity make fused silica a versatile material for refractory applications.
We strictly choose high purity silica sand (SiO2 > 99%) from Donghai/Xinyi as our raw material.
The silica sand is melted at high temperatures (2000-2300 ºC) to form amorphous silicon dioxide glassy ingot, which is then cooled. The products are further processed into fused silica lump, sand, and powder according to customer requirements.

High-Grade Fused Silica Sand for Refractory Applications in 25kg plastic woven bags on pallets. From Lianyungang Chemsize International Trading Co., Ltd.
Explore our High-Grade Fused Silica Sand for Refractory Applications. We are a leading manufacturer and supplier of premium silica products.
Fused Silica is produced using high purity crystal silica from China Donghai-Xinyi. It is electrically fused at temperatures ranging from 1800-2000ºC to create amorphous Silicon dioxide. The material is then specially engineered into various forms such as lumps, cullet, ingots, sand, grain, granular, and powder flour. These forms are specifically designed for making PV fused silica crucibles, thermal ceramics, refractories, EMC investment casting ceramic shells, and more.
