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 based on customer requirements.Detailed PhotosDiscover our Investment Casting Refractory Ramming Mass with Low Iron, perfect for induction furnace linings and ceramic welding repairs.Packaging & ShippingFused Silica Package and Delivery: 25kg Net Plastic Woven Bag on Pallet. Ideal for Investment Casting Refractory Ramming Mass with Low Iron.Lianyungang Chemsize International Trading Co., Ltd. presents Investment Casting Refractory Ramming Mass with Low Iron. Ideal for induction furnace lining and ceramic welding repairs.Fused 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 form amorphous Silicon dioxide. The material is then specially processed into lumps, cullet, ingots, sand, grain, granular, and powder flour forms. These 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 be free of foreign materials such as strings, plastic lines, carbon, wood, metal, or other contaminants.Any color dots are prohibited except for conditional black dots.Black spot diameter should not exceed 2mm.Total quantity of black dots 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, offers high-quality grains and powders for various industries.
