Spherical alumina Al2O3 powder overview

Alumina is an inorganic substance with a chemical formula of Al2O3. It is a high-hardness compound, also known as bauxite in mining, ceramics, and materials science. It is a white solid, insoluble in water, odorless and tasteless, and very hard in nature. Easy to absorb moisture but not deliquescence (no moisture absorption after burning). Alumina is a typical amphoteric oxide (corundum is alpha-shaped and belongs to the most densely packed hexagonal compound. It is an inert compound, slightly soluble in acids and alkalis, and resistant to corrosion. It is soluble in inorganic acids and alkali solutions, but almost insoluble In water and non-polar organic solvents; relative density (d204) 4.0; melting point 2050°C, boiling point 2980°C, ionize ionic crystals at high temperature, often used to make refractory materials.

Spherical alumina is a high hardness compound

Spherical alumina Al2O3 powder features: high filling density: large particle size, wide particle size distribution, high-density filling of rubber and plastic can be realized, low viscosity, good fluidity rubber compound; high thermal conductivity: and crystallization Compared with silica, the high bulk density can make the thermal conductivity and heat dissipation rate of the composite higher; low abrasiveness: due to its spherical shape, the kneader, molding machine and mold wear less.

Application of Spherical Alumina Al2O3 Powder

Alumina Al2O3 is suitable for a variety of wet and dry treatment processes. It can finely grind the rough surface of any workpiece and is one of the most economical abrasives. The hardness of this sharp water chestnut synthetic abrasive is second only to diamond, and is especially suitable for occasions with strict requirements for iron pollution. Used for the roughest cutting, it can also be made into a pebble shape to process precision-sized workpieces to achieve extremely low roughness. Due to its high density, sharpness, and rhombohedral structure, it is one of the fastest cutting abrasives.

Alumina Al2O3 is used to smelt high-quality bauxite to produce brown corundum, while high-quality aluminate is used to produce powdered corundum and white corundum. Their natural crystal structure makes them hard and tough. At the same time, they are often used as raw materials for bonded abrasive tools and coated abrasive tools. Alumina Al2O3 can be recycled many times, and the number of cycles depends on the grade of the material and the specific process. Most standard sandblasting equipment can be used.

Spherical alumina is mainly used in the following aspects:

1. Paint: enamel paint, wear-resistant paint, plasma spraying.

2. Ceramics: transparent ceramics, bio-ceramics, alumina ceramics.

3. Petrochemical products: high-efficiency catalysts, catalyst carriers, automobile exhaust purification materials.

4. Polishing materials: sub-micron/nano-level abrasive materials, monocrystalline silicon wafer polishing, precision polishing materials.

5. Illumination: Long afterglow phosphor raw material and rare earth tricolor phosphor raw material high pressure sodium tube, LED lamp, etc.

6. Electronic products: integrated circuit substrates, single crystal materials, far-infrared materials.

7. Cosmetics: cosmetic fillers.

8. Inorganic membrane materials.
