Hi Sanford. Thank you for your question.

Bauxite ultrafine powder can be used in many industries.

1. Aluminum smelting industry. Bauxite ultrafine powder can be used for national defense, aviation, automobile, electrical appliances, chemical industry, daily necessities, etc.

2. Precision casting. Bauxite clinker can be processed into fine powder and made into precision casting. Then it is used in the military, aerospace, communications, instrumentation, machinery and medical equipment departments.

3. Refractory products. High bauxite clinker refractory degree can be up to 1780 degrees, with advantages of strong chemical stability and good physical properties.

4. Aluminum silicate refractory fiber has the advantages of light weight, high temperature resistance, good thermal stability, low thermal conductivity, small heat capacity and mechanical vibration resistance. It is usually used in steel, non-ferrous metallurgy, electronics, petroleum, chemical, aerospace, atomic energy, national defense and other industries. Aluminum silicate refractory fiber is a kind of white cotton which is melted at high temperature, blown by high-pressure and high-speed air or steam and cooled by putting high-alumina clinker into high-temperature electric arc furnace with melting temperature about 2000-2200 ℃. It can be pressed into fiber blankets, boards or woven into cloth instead of smelting, chemical, glass and other industrial high-temperature furnace lining refractory bricks. Firefighters can use refractory fibers to make clothes.

5. Bauxite ultrafine powder can produce aluminous cement and abrasive materials.
