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 in 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.

Fused 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 engineered into various forms such as lumps, cullet, ingots, sand, grain, granular, and powder flour. These forms are designed 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 also 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 usually ship via DHL, UPS, FedEx, or *** with a delivery time of 3-5 working days. By sea, it can take 7-40 days depending on the distance.
