Our company specializes in the production of high-purity fused silica, a versatile material ideal for refractory applications. Fused silica is created by melting high-purity quartz sand at temperatures between 2000-2300 ºC, resulting in a stable, low-expansion, and highly pure glass material.
We carefully select silica sand with a purity of SiO2>99% from Donghai/Xinyi as our raw material. After the melting process, the silica sand transforms into amorphous silicon dioxide glassy ingots, which are further processed into fused silica lumps, sand, and powder to meet our customers' specific needs.
Choose Lianyungang Chemsize International Trading Co., Ltd. for top-quality fused silica products tailored to your requirements.

Explore images showcasing the production process and quality control of our professional Fused Silica Cullet for Epoxy Molding Compound. Witness the precision and excellence in every step.
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.

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 usually ship via DHL, UPS, FedEx, or *** with delivery in 3-5 working days. Sea freight may take 7-40 days depending on the distance.
