Superior Grade Bauxite Powder

We are manufacturing and exporting Calcined Bauxite in Shizuishan, Ningxia Hui, China, this is also known as bauxite or bauxite, the main component is alumina, hydrated alumina containing impurities, is a kind of earthy minerals. White or off-white, brown or light red due to iron. Density 3.45g/cm3, hardness 1~3, opaque, crisp. Extremely hard to melt. Insoluble in water, soluble in sulfuric acid, sodium hydroxide solution. It is mainly used for aluminum smelting and refractories.

Product performance: It has the advantages of light weight, high temperature resistance, good thermal stability, l ow thermal conductivity, small heat capacity and mechanical vibration resistance. Metallurgy, electronics, and stone The high-alumina clinker is placed in a high-temperature electric arc furnace with a melting temperature of about 2,000 to 2,200A C. After high-temperature melting, high-pressure high-speed air or steam injection, and cooling, it becomes a white "cotton". - Aluminosilicate refractory fiber.

Product Usage:
1. Aluminum smelting industry. For defense, aviation, automotive, electrical appliances, chemicals, daily necessities, etc.
2. Precision casting. Bauxite clinker is processed into fine powder and cast into molds. For the military, aerospace, communications, instrumentation, machinery and medical devices sector.
3. For refractory products. High alumina bauxite clinker has high refractoriness up to 1780A C, high chemical stability and good physical properties.
