Refractory material

Our company produces fused quartz sand and fused quartz powder for various types of refractory materials. We sincerely welcome new and old customers to negotiate for use.

Features of fused silica sand acting on refractory industry:

Minimum linear expansion coefficient, minimum thermal conductivity, good thermal shock resistance,

The thermal shock resistance of fused quartz sand is the best (at 1200 ℃~water-cooled), and there is no crack after 10 times. Among all refractory materials, the linear expansion coefficient is the minimum (thermal expansion rate at 1000 ℃ is 0.05); The thermal conductivity is the lowest, 0.836W/(m·K) (0.02cal/cm. s·℃) at 1000 ℃; The thermal shock resistance is the best (at 1200 ℃~water-cooled shock resistance), and no cracks are generated after 10 times. The company produces fused quartz sand for refractory materials, Grade II and Grade III products, which are ideal raw materials for refractory silica bricks, furnace lining materials, quartz nozzles, quartz saggers and other products.

Common specifications: 5-3mm, 3-1mm, 1-0mm, 1-0.5mm, 0.5-0.2mm, 0.2-0.1mm, 50-100 mesh, 200 mesh, 325 mesh, 400 mesh, etc. can also be produced according to customer requirements.
