Fused Silica Grain as Refractory Materials

Our fused silica grain has different applications as refractory materials due to its ability to withstand continuous exposure to the combination of heat, corrosion, abrasion and impact. Choosing the proper refractory material for an application is critical because poor quality materials can lead to excessive maintenance and equipment failure – resulting in recurring downtime, lost production and erosion of profits.

Used and Trusted across Industries

Dinglong fused silica sands are engineered grains made from high purity silica, using electric fusion melting process to ensure the highest quality. At 99.98% purity, our fused silica grain is inert, has excellent chemical stability and has extremely low electrical conductivity. Our fused silica grains are used and trusted across industries at home and abroad because we attach great importance to the reliability and consistency of our products and to build strategic partnership and friendship with our customers.
