Discover our high-quality fused silica products:
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 fused silica a versatile material for refractory applications.
We strictly select high-purity silica sand (SiO2 > 99%) from local 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 cooled. We offer fused silica lumps, sand, and powder tailored to customer requirements.
Discover high-quality Fused Quartz Powder for refractory applications from Lianyungang Chemsize International Trading Co., Ltd. Perfect for investment casting, epoxy molding, and precision casting supplies.
Fused Silica Package and Delivery: Fused Silica Plastic Woven Bag of 25kg Net each, Then on Pallet.
Lianyungang Chemsize International Trading Co., Ltd. offers high-quality Fused Quartz Powder for refractory applications. Our product is ideal for various industrial uses.
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 resulting material is 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.
