Where can brown fused alumina be used? What are the characteristics of brown fused alumina?

Brown fused alumina has a wide range of applications, and is widely used in the manufacture of ceramics and sandblasting and polishing, and is one of the most basic abrasives. Mainly the use of bauxite, carbon materials and iron filings three raw materials in the electric furnace after melting and reduction and made of tan artificial corundum, with a variety of two properties, in industrial production plays an irreplaceable role, wear resistance is particularly prominent, some industrial equipment parts are inseparable from brown corundum. At present, brown fused alumina has a lot of room for development in mechanical processing, because its strength and hardness are higher than other similar materials, and the cost performance is higher.

For example, in the field of chemical production, brown fused alumina is often used in the production of some chemical components or chemical reaction vessels. Because chemical products often have a certain degree of corrosiveness, the requirements for chemical equipment are naturally higher, and in order to ensure the long-term use of chemical equipment, it is natural to consider the actual performance and effect of operation before processing. Brown fused alumina itself combines the excellent properties of a variety of materials, is chemically stable, and can resist a certain degree of corrosion, so it has naturally become the preferred material in industrial production.
