What are the applications of spherical alumina?
Introduction of spherical alumina
Spherical alumina has excellent mechanical properties and is often used as a grinding medium in various mills. Spherical alumina has high compressive strength and wears resistance. Spherical alumina has higher filling performance, and its particles have higher spherical velocity and wider particle size distribution. It can fill rubber and plastics with high density to obtain a mixture of low viscosity and good fluidity.
Secondly, the spherical oxidation furnace also has a higher thermal conductivity. Because it can be filled with high density, compared with crystalline silicon powder, a mixture with high thermal conductivity and good heat dissipation can be obtained.
The main features of spherical alumina
1. High filling
It has high particle sphericity and wide particle size distribution. It can fill rubber and plastics with high density and can obtain a mixture with low viscosity and good fluidity.
2. High thermal conductivity
Because it can be filled with high density, compared with crystalline silicon powder, a mixture with high thermal conductivity and good heat dissipation can be obtained.
3. Low abrasion
Because of its spherical appearance, the abrasion of equipment such as mixer, molding machine and mold is greatly reduced, and the service life of the equipment can be prolonged.
Can alumina be inhaled into the body?
Alumina is one of the less toxic substances and only shows toxic effects at high concentrations. Avoid inhaling aluminum oxide dust. Long-term inhalation of aluminum oxide may cause pneumoconiosis, coughing and dyspnea due to exertion, diffuse reticulated shadows on chest X-rays, and limited lung function. In severe cases, death may be due to respiratory failure or pneumonia.
Application of Spherical Al2O3 Powder
1.Coating: ceramic coating, wear-resistant coating, plasma spraying.
2.Ceramics: transparent ceramics, bio-ceramics, alumina ceramics.
3.Petrochemical industry:high-efficiency catalysts, catalyst carriers, automotive exhaust purification materials.
4.Polishing materials: submicron/nano abrasives, single crystal silicon wafer grinding, precision polishing materials.
5.Lighting: long afterglow phosphor raw materials and rare earth three primary color phosphor materials, high-pressure sodium tubes, LED lights, etc.
6.Electronic products: integrated circuit substrates, single-crystal materials, far infrared materials.
7.Cosmetics: cosmetic fillers.
8. membrane materials：Inorganic membrane materials.
How to store Al2O3 powder?
Al2O3 powder should be stored in a dry, cool and sealed environment, and not exposed to the air. In addition, heavy pressure should be avoided and transported as ordinary items.
