Sol en aluminium, également connu sous le nom de minerai d'aluminium, est un minerai industriel important. Son composant principal est l'alumine (Al2O3), et il contient également certaines impuretés. L'utilisation de la bauxite est très large, comprenant principalement:

1.la bauxite est l'une des principales matières premières pour la production d'aluminium. Par fusion à haute température, la bauxite peut être transformée en métal aluminium. Aluminum is an important raw material for making various aluminum alloys and aluminum products. It is widely used in national defense, aviation, electrical appliances, chemical and daily living supplies.

2.Refractory material: Aluminum alum -cooked materials are widely used for refractory materials due to the stable properties of its high temperature. These materials are used as lining in high -temperature industrial furnaces, such as furnaces and furnaces in steel, verre, ceramics and chemical production.

3.Precision casting: bauxite can be processed into fine powder for making molds for precision casting technology, and then used for precision casting of military industry, aérospatial, communication instruments, machinery and medical equipment.

4.Aluminum refractory fiber: bauxite is also the basic raw material for producing aluminum refractory fibers. This kind of refractory fiber has the characteristics of light quality, résistance aux hautes températures, good thermal stability, faible conductivité thermique, and mechanical vibration resistance. application. It can also be used to create alternatives to fire tiles, such as high -temperature kiln lining.

5.Other applications:bauxiteis also used to manufacture alum to cement, grinding materials, céramique, etc.. In the chemical industry,bauxitecan be used to produce various compounds of aluminum for the production of chemical products.
