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 according to customer requirements.Detailed PhotosDiscover our high-quality Silica Flour for Investment Casting Industry, perfect for precision foundry supplies and high-temperature applications.Packaging & ShippingOur Fused Silica Package includes 25kg plastic woven bags, delivered on pallets for convenience.
