Fused Silica Production Process
Fused silica is a high-purity quartz sand that has been melted to form glass. 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 specifications.
Discover our Fine Fused Silica Powder with Fe2O3 content below 0.003%. Perfect for various applications like investment casting and refractory materials.
Fine Fused Silica Powder with Fe2O3 content below 0.003%, packaged in 25kg plastic woven bags on pallets. Supplier: Lianyungang Chemsize International Trading Co., Ltd.
Explore our Fine Fused Silica Powder with Fe2O3 content below 0.003%. Perfect for various applications like investment casting and refractory materials. Discover high purity silica for your needs.
Fused Silica is a high purity crystal silica material produced by electrically fusing amorphous Silicon dioxide at temperatures ranging from 1800-2000ºC. Our Fused Silica is specially engineered into various forms such as lumps, cullet, ingots, sand, grain, granular, and powder flour, ideal for manufacturing PV fused silica crucibles, thermal ceramics, refractories, EMC investment casting ceramic shells, and more.
Q1: Can I request a sample order for fused silica products?
A: Yes, we offer free samples shipped via ***/FEDEX/DHL. Mixed samples are acceptable.
Q2: What is the lead time for samples?
A: Samples are typically sent within 3-5 days.
Q3: Is there a minimum order quantity for fused silica sand?
A: No, but lower quantities may result in higher average costs.
Q4: How are the goods shipped and what is the delivery time?
A: We ship via DHL, UPS, FedEx, or *** with delivery in 3-5 working days. Sea shipments may take 7-40 days depending on the distance.
Q5: What is the process for ordering fused silica powder products?
