Pan designates the percentage of fused silica passing the last reported screen for each size.
Used in industries such as thermal ceramic, refractory, investment casting, EMC, solar crucible, quartz marble, powder coating, etc.
The particle size can be produced as per customer's special requirement.
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.
Discover our high-quality Fused Silica for various applications like precision casting, investment casting, refractories, and more.
