Fused silica, derived from high purity quartz sand, is ideal for refractory applications due to its high volume stability, low volumetric expansion, and exceptional purity.Our raw material is carefully selected from high purity silica sand (SiO2>99%) sourced from Donghai/Xinyi. Through a rigorous process of melting at temperatures between 2000-2300 oC, the silica sand transforms into amorphous silicon dioxide glassy ingot, which is then cooled and processed into fused silica lump, sand, and powder to meet our customers' specific needs.Detailed PhotosDiscover our premium Fused Silica Powder for Precision Casting, ideal for high-quality applications.
