Description
Product Description
Bauxite also known as bauxite or bauxite, the main component is alumina, containing impurities of hydrated alumina, is an earth-like mineral. Light burnt bauxite, also known as light burnt powder, is the raw material of water purification agent polyaluminum chloride, is the mineral powder material produced by bauxite processing. White or off-white, brown yellow or light red because of iron. Density 3.45g/cm3, hardness 1~3, opaque, brittle. Extremely difficult to melt. Insoluble in water, soluble in sulfuric acid, sodium hydroxide solution. Mainly used for aluminum smelting, refractory materials.
Its composition is very complex, is a variety of geological sources are very different hydrous alumina ores general name. Such as diaspore, diaspore and diaspore (Al2O3·3H2O); Some are accompanied by diaspore and kaolinite (2SiO2·Al2O3·2H2O); Some are mainly kaolinite, and with the increase of kaolinite content, it is composed of general bauxite rock or kaolinite clay. Bauxite is generally formed by chemical weathering or exogenesis, there are few pure minerals, always contain some impurity minerals, more or less containing clay minerals, iron minerals, titanium minerals and detrital heavy minerals and so on.

Product use:
⑴ aluminum smelting industry. Used in national defense, aviation, automobiles, electrical appliances, chemicals, daily necessities and so on.
⑵ Precision casting. Bauxite clinker is processed into fine powder and cast into mold after precision casting. Used in military, aerospace, communications, instrumentation, machinery and medical equipment departments.
(3) For refractory products. High bauxite clinker refractoriness up to 1780℃, strong chemical stability, good physical properties.
⑷ Aluminum silicate refractory fiber. It has the advantages of light weight, high temperature resistance, good thermal stability, low thermal conductivity, small heat capacity and mechanical shock resistance. Used in steel, nonferrous metallurgy, electronics, petroleum, chemical industry, aerospace, atomic energy, national defense and other industries. It is to put high aluminum clinker into the melting temperature of about 2000~2200℃ high temperature arc furnace, after high temperature melting, high pressure high speed air or steam blowing, cooling, it becomes white "cotton "- aluminum silicate refractory fiber. It can be pressed into fiber blanket, board or woven cloth instead of smelting, chemical, glass and other industrial high-temperature kiln lining refractory brick.
