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 create amorphous silicon dioxide glassy ingots, which are then processed into fused silica lumps, sand, and powder based on customer requirements.Detailed PhotosAffordable Fused Silica options from a trusted factory. Ideal for ceramic welding, investment casting, and refractory applications. Choose from a variety of sizes and purity levels.Packaging & ShippingGet your hands on affordable Fused Silica options from our trusted factory. Available in various sizes for different applications. Contact us today!Discover affordable fused silica options from our trusted factory, offering a wide range of sizes for various applications in industries like glass and investment casting.Fused Silica Product DescriptionFused Silica Making ProcessFused Silica is produced from high purity crystal silica sourced from China Donghai-Xinyi. It is electrically fused at temperatures ranging from 1800-2000oC to create amorphous Silicon dioxide. The material is then specially processed into various forms such as lumps, cullet, ingots, sand, grain, granular, and powder flour. These forms are specifically designed for manufacturing PV fused silica crucibles, thermal ceramics, refractories, EMC investment casting ceramic shells, and more.Fused Silica Sand Appearance and Specifications:Must not contain any unfused parts.Should not have any foreign materials like string, plastic, carbon, wood, metal, or other contaminants.Only conditional black dots are allowed; all other color dots are prohibited.Black spot diameter should not exceed 2mm.Total black dots quantity should be less than 10 per square meter when opening the big bag.For any inquiries, please contact Lianyungang Chemsize International Trading Co., Ltd.Chemsize Fused Silica ProductsChemsize, a leading manufacturer of Fused Silica grains and powders, offers high-quality materials for various industries.
