Pan designates the percentage of fused silica passing the last reported screen for each size.
Fused Silica features extremely low coefficient of thermal expansion, consistent chemistry, and carefully controlled particle size distribution.
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 the customer's special requirement.
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, 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.
Explore our Investment Casting Grade Fused Silica with Low Iron Content for high clarity pictures. Ideal for various applications, this material offers exceptional purity and thermal shock resistance.
Our Investment Casting Grade Fused Silica with Low Iron Content is packaged in 25kg plastic woven bags and palletized for delivery.
Explore our Investment Casting Grade Fused Silica with Low Iron Content for superior quality in casting applications. High purity, low impurities, and thermal shock resistance make it ideal for various casting needs.
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 ideal for manufacturing PV fused silica crucibles, thermal ceramics, refractories, EMC investment casting ceramic shells, and more.
