Fused silica is 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.
We strictly choose 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 ingot, which is then cooled. The products are further processed into fused silica lump, sand, and powder according to customer requirements.

Fused Silica is produced using high purity crystal silica from China Donghai-Xinyi. It is electrically fused at temperatures ranging from 1800-2000ºC to create amorphous Silicon dioxide. Our products are engineered into lumps, cullet, ingots, sand, grain, granular, and powder flour forms, specifically designed for making 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 ship via DHL, UPS, FedEx, or *** with delivery times of 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?
Q6: Can my logo be printed on the packages?
A: Yes, please inform us before production and confirm the design based on our sample.
Q7: How are faulty products handled?
A: Our products have a low defective rate (<0.2%). If any issues arise, we will send replacements and cover any losses.
