Fused Silica Production Process
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, such as aluminum launders.
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 high temperatures (2000-2300 ºC) to form amorphous silicon dioxide glassy ingots, which are then processed into fused silica lumps, sand, and powder based on customer requirements.

Fused Silica Package and Delivery: 25kg Net Plastic Woven Bag on Pallet. Ideal for Investment Casting Refractory Ramming Mass with Low Iron.
Lianyungang Chemsize International Trading Co., Ltd. presents Investment Casting Refractory Ramming Mass with Low Iron. Ideal for induction furnace lining and ceramic welding repairs.
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 form amorphous Silicon dioxide. The material is then specially processed into lumps, cullet, ingots, sand, grain, granular, and powder flour forms. These are specifically designed for manufacturing PV fused silica crucibles, thermal ceramics, refractories, EMC investment casting ceramic shells, and more.
