Aluminum oxide, commonly known as alumina, is a versatile and hard-wearing ceramic material that consists of aluminum and oxygen atoms. It exhibits exceptional hardness and is used in a wide array of applications, including as an abrasive material in sandpapers and grinding wheels due to its ability to cut and shape various surfaces. Additionally, aluminum oxide serves as an insulating material in electronics, a catalyst in chemical processes, and as a refractory material in high-temperature environments such as furnaces and crucibles. Its combination of hardness, high melting point, and electrical insulating properties makes aluminum oxide a crucial material in industries ranging from manufacturing to electronics.

Description:
Brown Fused Alumina is fused and crystallized under high temperature from a mixture of bauxite and other and other raw materials. It is characterized by its high hardness,good toughness and shape in size. Abrasives tools made of it are suitable for grinding metals of high-tensile strength such as: carbon steel,general-purpose alloy steel,annealed malleable iron and hard broze,etc.It also can be used as refractory materials.
Application:
1. Abrasive: Produce ceramic gring wheel, resinoid gringding wheel, Grinding stone, Gringing block, sand paper, sand cloth,sand belt, polish wax, abrasive paste, coating etc..
2. Refractory material: Mainly used for abrasion and high temperature resiatant, inoxidizable aggregate and filling of shaped and monolithic refractory in steel metallurgy, various industrial stoves, electric furnace etc..
3. Sandblasting abrasive: Mainly used for various material workpieces to decontaminate, derusting, prevent corrosion,remove oxide skin etc..
4.Abrasion resistance ground: Mainly used for non-slip of airport and road, chenmical factory
board paving.
5.Precision casting: Investment casting technics of stainless steel and aluminium casting in coating.

Tabular Alumina Al2O3 99.2% min
Tabular Alumina: The plate-like crystal structure has small pores and many closed pores, and the porosity is roughly the same as that of fused corundum. It has high purity, good volume stability and minimal reheating shrinkage. The refractory or castable used for production has good thermal shock stability and bending strength after high-temperature treatment, but the price is higher than that of other alumina. High fire resistance; High corrosion resistance; High erosion resistance; High thermal shock stability; High strength and good toughness; Stable chemical properties. Tabular corundum is a kind of pure sintered corundum with complete shrinkage without adding any additives such as It has the characteristics of coarse crystal and good development crystal structure. The plate-like crystal structure has small pores and many closed pores, and the porosity is roughly the same as that of fused corundum. It has high purity, good volume stability and minimal reheating shrinkage.
Alumina (Aluminium Oxide) is the most widely used oxide ceramic material. Its applications are widespread, and include spark plugs, tap washers, abrasion resistant tiles, and cutting tools. Very large tonnages are also used in the manufacture of monolithic and brick refractories.
High purity aluminum oxide
is the raw material for sapphire crystal. This type of pressed pellets are made from ultra high purity alumina. It is designed to provide high filling in crucibles used to make sapphire single crystals. The alumina materials RBST supplied are produced with latest eco-friendly and high technology. As a supplier for advanced materials, we continuously improving the service by cooperate with the manufacturers with high efficiency large volume production.
High purity alumina powder is a compound, commonly known as aluminum oxide (Al2O3). It is odorless, white, crystalline powder. It has very high melting point. It is insoluble in water and difficult solubility in mineral acids and strong alkali. The variety formed at very high temperature is quite inert chemically. It is amphoteric in nature, and is used in various chemical, industrial and commercial applications.
Alumina, also known as activated alumina is manufactured from aluminium hydroxide by dehydroxylating it in a way that produces a highly porous material; this material can have a surface area significantly over 200 square meters/g. The compound is used as a (to keep things dry by absorbing water...
