Calcined Bauxite
Calcined bauxite is also called aluminous soil. Its main component is aluminum oxide (Al2O3), which is a hydrated aluminum oxide containing impurities and is a soil-like mineral. It is white or grayish white. Some are brownish yellow or light red due to iron. The density of bauxite is 3.9 – 4g/cm3 and the hardness is 1 – 3. It is opaque and brittle. Moreover, it is extremely difficult to melt and insoluble in water. However, refractory bauxite can be dissolved in sulfuric acid and sodium hydroxide solution. We mainly use it for aluminum smelting and making refractory materials.
Alumina Refractory Calcined Bauxite Properties
Excellent high temperature resistance: aluminium bauxite can maintain stable physical and chemical properties under high temperature environment.
Good corrosion resistance: its main component is aluminum oxide (Al2O3). This allows it to be used stably for a long time in acidic, alkaline or other corrosive environments.
High mechanical strength: calcined bauxite can withstand physical impact and wear in equipment operation in refractory materials. So, it extends the service life of the material.
Good thermal conductivity: bauxite has moderate aluminium oxide thermal conductivity, which is conducive to uniform distribution and conduction of heat. This also improves the thermal efficiency and energy utilization efficiency of the equipment.
Stable chemical properties: alumina refractory products is not easy to react or dissolve with other materials.
Diverse applications: calcined bauxite can be used to produce various types of refractory materials to meet the needs of different industrial fields. Such as refractory bricks, high temperature castable refractory and refractory fibers.

Aluminium Oxide Calcined Bauxite Uses
The main calcined alumina bauxite uses are as follows. The YouTube homepage of Kerui has more detailed uses and methods of calcined and fused alumina bauxite products.
- Aluminum smelting industry. Used in national defense, aviation, automobiles, electrical appliances, chemicals, daily necessities, etc.
- Precision casting. Alumina clinker is processed into fine powder and made into a mold for precision casting. Used in military industry, aerospace, communications, instrumentation, machinery and medical equipment departments.
- Used for refractory products. High-alumina alumina clinker has a refractoriness of up to 1780℃(3236℉). It has strong chemical stability and good physical properties.
- Using magnesia and alumina clinker as raw materials, adding appropriate binders for casting the overall lining of steel ladle has a very good effect.
- You can use it to make alumina refractory cement for sale, grinding materials, ceramic industry and chemical industry can make aluminum materials.
