Uses of alumina

High-purity, uniform particle size alumina is easy to disperse, chemical properties are also very stable, high temperature shrinkage performance is also moderate, has a good sintering performance conversion rate, is the production of heat-resistant, wear-resistant, corrosion-resistant products of the basic raw materials.

(1) Production of sapphire (Sapphire), also known as corundum. It is a single crystal of alumina (α-Al2O3). It has excellent optical properties, mechanical properties and chemical stability, high strength, high hardness, erosion resistance, and can work under high temperature conditions close to 2000 °C. The raw material for the production of quartz sand (also known as silica sand) is also a raw material for quartz refractory and firing ferrosilicon.

(2) Alumina has a variety of functions such as electricity, optics, chemistry, biology, heat, and mechanics. The uses include integrated circuit substrates, optical fibers, control chemical reactions, artificial skeletons, artificial tooth roots, bearings, heat resistance, thermal insulation structural materials, precision mechanical parts.

Product advantages

Forsman alumina powder products are classified according to different classifications: according to the microscopic form, there are alumina powder, alumina powder (spherical), alumina powder (flakes); The product particle size distribution span is large; According to the molded products: alumina powder (granulation). According to customer needs, 25 kg and 100 kg products with particle sizes from 75 to 250 μm can be supplied with industrial production and can be customized with other particle sizes.
