Product Description

Aluminum oxide is an inorganic substance with the chemical formula Al2O3. It is a high-hardness compound with a melting point of 2054°C and a boiling point of 2980°C. It is an ion crystal that can be ionized at high temperatures and is often used to make refractory materials.
Industrial alumina is prepared from bauxite (Al2O3·3H2O) and diaspore. Al2O3 with high purity requirements is generally prepared by chemical methods. Al2O3 has many isomorphic crystals, more than 10 of which are known, and there are three main crystal forms, namely α-Al2O3, β-Al2O3, and γ-Al2O3. Different structures have different properties, and they are almost completely converted into α-Al2O3 at high temperatures above 1300°C.

1. Manufacturing strengthened glass
2. Aluminum oxide is suitable for a variety of wet and dry processing processes and can polish the rough surface of any workpiece into fine details. It is one of the most economical and affordable abrasives. This sharp and angular synthetic abrasive has a hardness second only to diamond and is especially suitable for use when there are strict requirements for iron contamination. Used for the roughest cutting, it can also be made into a pebble shape to process workpieces with precise dimensions to achieve extremely low roughness. It is one of the fastest cutting abrasives due to its high-density, sharp, diamond-shaped structure.
3. Applicable industrial scope: aerospace industry, automotive industry, consumer goods processing, casting/die-casting, OEM distributors, semiconductor industry and other different fields.
4. Applicable process scope: pretreatment before surface plating, painting, glazing and coating of PTFE; deburring and pot scale removal of aluminum and alloy products; mold cleaning; pretreatment before metal sandblasting; dry grinding and wet grinding Grinding; precision optical refraction; grinding of minerals, metals, glasses and crystals; glass engraving and paint additives.
5. Alumina is divided into calcined alumina and ordinary industrial alumina. Calcined alumina is an essential raw material for the production of antique bricks, while industrial alumina can be used to produce microcrystalline stones. In traditional glazes, alumina is often used as an additive. white. As antique bricks and microcrystalline stones are favored by the market, the consumption of alumina is also increasing year by year.
