Pan designates the percentage of fused silica passing the last reported screen for each size.
Fused Silica features extremely low coefficient of thermal expansion, consistent chemistry, and carefully controlled particle size distribution.
Fused Silica is used in industries such as thermal ceramic, refractory, investment casting, EMC, solar crucible, quartz marble, powder coating, etc.
The particle size can be produced as per the customer's special requirement.
Company name: Lianyungang Chemsize International Trading Co., Ltd.
Product Description:
At Lianyungang Chemsize International Trading Co., Ltd., we specialize in the production of high-quality fused silica. Our fused silica is derived from high purity quartz sand, melted at temperatures between 2000-2300 ºC to create a glassy ingot of amorphous silicon dioxide. This material offers exceptional stability, low volumetric expansion, and unmatched purity, making it ideal for a wide range of refractory applications.
We meticulously select locally sourced high purity silica sand with a SiO2 content exceeding 99% for our production process. Our fused silica products are available in various forms, including lumps, sand, and powder, tailored to meet the specific requirements of our customers.

Explore our gallery showcasing our cutting-edge fused silica production facility and stringent quality control measures. Witness our commitment to delivering high-quality fused silica powder for refractory applications.
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 engineered into various forms such as lumps, cullet, ingots, sand, grain, granular, and powder flour. These forms are specifically 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 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. By sea, it 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 undergo strict quality control, with a defective rate of less than 0.2%. If any issues arise, we will replace the products and cover any losses.
