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 source high purity silica sand (SiO2 > 99%) from local 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.Detailed PhotosDiscover our Premium Fused Silica Grains for Investment Casting, offering high clarity and quality for superior results.Packaging & ShippingFused Silica Package and Delivery: Premium Fused Silica Grains for Investment Casting in 25kg plastic woven bags on pallets. From Lianyungang Chemsize International Trading Co., Ltd.Product Description:Explore our top-grade Premium Fused Silica Grains for Investment Casting, sourced from leading suppliers of high-purity quartz materials.Fused Silica Product DescriptionFused Silica ProductsFused Silica is a high purity crystal silica material produced by electrically fusing amorphous Silicon dioxide at temperatures ranging from 1800-2000oC.
