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 to create a glassy ingot of amorphous silicon dioxide. With exceptional high volume stability, low volumetric expansion, and unmatched purity (SiO2>99%), our fused silica is ideal for various refractory applications.
We meticulously select our raw materials from the pristine sources of Donghai/Xinyi, ensuring the highest quality standards. Through a precise fusion process at temperatures ranging from 2000-2300 ºC, the silica sand transforms into a versatile material available in lump, sand, and powder forms, tailored to meet our customer's specific requirements.

Fused Silica is produced using high purity crystal silica from China Donghai-Xinyi. It is electrically fused at temperatures between 1800-2000ºC to create amorphous Silicon dioxide. The resulting material is engineered into various forms such as lumps, cullet, ingots, sand, grain, granular, and powder flour. These forms are ideal for manufacturing PV fused silica crucibles, thermal ceramics, refractories, EMC investment casting ceramic shells, and more.
