What process should be followed in the processing of white corundum powder?

The traditional white corundum powder processing process is to place the raw materials in a high-temperature electric arc furnace to make corundum blocks, which are processed and refined to produce white corundum powders of different sizes. With the improvement of technology, the current white corundum powder processing process has been greatly different.

Nowadays, the preparation of white corundum powder is to first shape the powdery white corundum solid, and continue to heat it under the action of lower than its melting point. During the heating process, a catalyst and a binder are added to bond, fuse and crystallize each other . white fused alumina propertiesThe main principle is that the powder surface has a larger surface area and higher surface energy, so chemical reactions such as polycrystalline transformation, recrystallization, and eutectic occur.

Compared with the traditional white corundum processing flow, the cost of the new processing flow has been greatly reduced, and the newly made white corundum powder has high hardness, good polishing and high self-sharpening properties, and has become a new type of abrasive powder at home and abroad .

Considering from the raw material: white corundum is made from high-quality alumina powder and refined by capacitors.abrasive factory china It is suitable for manufacturing ceramics, resin cemented abrasive tools, as well as grinding, polishing, sandblasting, precision casting, etc.

The country is making great efforts to control the environmental protection of alumina powder, shutting down outdated production facilities and illegal sewage disposal companies, resulting in a tight supply of alumina powder. Therefore, some white There are fewer manufacturers, and there is a situation of short supply, which leads to price increases.
