Lianyungang Chemsize International Trading Co., Ltd. offers high-quality fused silica with various particle sizes to meet your specific requirements.
Fused Silica features an extremely low coefficient of thermal expansion, consistent chemistry, and a carefully controlled particle size distribution. This ensures optimal performance and reliability in various applications.
Fused Silica is widely used in industries such as thermal ceramic, refractory, investment casting, EMC, solar crucible, quartz marble, and powder coating. Its versatility makes it an essential material in many manufacturing processes.
Our fused silica is available in various sizes, including:
Custom particle sizes can also be produced to meet your specific requirements.
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 it a very useful and versatile material for refractory applications, such as aluminum launders or other highly cyclical applications.
At Lianyungang Chemsize International Trading Co., Ltd., we strictly choose high purity silica sand (SiO2 > 99%) from the local Donghai/Xinyi area as our raw material. The silica sand is melted at high temperatures (2000-2300 ºC) to form an amorphous silicon dioxide glassy ingot, which is then cooled. We further process the products into fused silica lumps, sand, and powder according to our customers' requirements.
Introducing our Superior Fused Silica Flour for Foundry Applications. Our high-quality Fused Silica grains are finely crushed to create ultrafine powder. Perfect for investment casting and refractory materials. Choose the best for your foundry needs.
Our high-quality fused silica flour is perfect for foundry applications. With its fine texture and superior purity, it's the ideal choice for investment casting and refractory materials. Trust our top-notch product for exemplary results.
Fused Silica is made of high purity crystal silica from China Donghai-Xinyi by electrically fusing (fusing temperature 1800-2000ºC) to amorphous Silicon dioxide. It is then specially engineered into lumps, cullet, ingots, sand, grain, granular, and powder flour form. These forms are designed for making PV fused silica crucible, thermal ceramic, refractory, EMC investment casting ceramic shell, and more.
