Refractory clay from China The building materials industry produces glass kilns for high alumina cement kilns, phosphates, high alumina bricks, and high alumina bricks. Clay calcined alumina and then mixed with limestone to make alumina cement, which has rapid setting ability and corrosion resistance properties, heat and strong resistance.

Refractory clay from China, polishing abrasive industry, chemical industry, ceramic industry, is also an important purpose. After arc smelting high alumina clay, the abrasive material, fused corundum abrasive is the most widely used abrasive at present, and abrasive products account for 2/3. High alumina clay, which can be used to produce various aluminum compounds, such as aluminum sulfate, aluminum hydroxide, aluminum trichloride, aluminum potassium sulfate and other chemical products. Ceramic industry, hard clay, semi-hard clay, can be used to manufacture ceramics, ceramic raw materials for building ceramics industry.

In addition, alumina clays are also used in oil wells, oil purification as proppants, agricultural promotion as fertilizer agents, as well as slippery, wear-resistant, paving materials, and more. Hard clay is also used to control a new refractory insulation material - refractory fiber, which has high temperature, heat conduction, acid, sound absorption and light, etc., and is widely used in metallurgy, machinery, electronics, glass, ceramics and other industries.
