Pan designates the percentage of fused silica passing the last reported screen for each size.
Fused Silica features an extremely low coefficient of thermal expansion, consistent chemistry, and carefully controlled particle size distribution.
Fused Silica is 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.
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 based on customer requirements.
