As we all know, bauxite has a wide range of uses and is often used in industry, and bauxite is classified differently according to its content and specifications, and its production process is also different. The bauxite clinker, bauxite raw meal and high alumina powder that are often used are very different, so today's diamond refractory material will show you the difference between bauxite and high alumina powder.
The difference between bauxite and high alumina powder
Bauxite, also called bauxite, is mainly composed of alumina, which is generally an earthy mineral containing hydrated alumina containing impurities. Because of the iron element, it is mostly light red and brown, but most of them are white or gray. Bauxite hardness is 1~3, density is 3.9~4g/cm3, opaque and brittle. Hard to melt. Insoluble in water, soluble in sulfuric acid.
The composition of high-alumina powder and bauxite are the same, but they are called differently. They have been deeply processed in the production process, but they are generally the same, and no one makes any difference.
What are the uses of bauxite
When it comes to the use of bauxite, we have to say a few words. There are two main uses of bauxite, one is the application of metal, and the other is the application of non-metal.
Metal application
The main function of bauxite in metals is to produce aluminum. After all, metal aluminum rarely exists in the form of natural aluminum in nature. Whether it is oxide or hydroxide, aluminum is the second most important metal in the world after steel, so the widely distributed natural bauxite will naturally become a source of extraction. Raw material of aluminum.
Non-metallic applications
1. As a refractory material: Bauxite clinker is a common refractory and anti-corrosion material in the industry. Its high temperature resistance is about 1700 degrees. In some electric furnaces and blast furnaces, its refractory performance is much better than that of ordinary clay refractory bricks.
2. Making casting coatings: Bauxite is mostly used for casting coatings, mainly made of clinker after being processed into fine powder, such as die casting coatings, etc., which can be used in military, aerospace, instrumentation, etc.
3. As a castable: using magnesia and bauxite clinker as raw materials, adding appropriate binders to cast the overall lining of the steel ladle, the effect is very good.
4. As abrasive: It can be used to produce various aluminum compounds in abrasive materials, alumina cement, ceramic industry and chemical industry.
The above is the difference between bauxite and high alumina powder introduced by King Kong Refractory. Each product has its own characteristics. We should choose according to the actual situation, and hope to help everyone.
