What Are The Application Scope Of Calcined Alumina Micro Powder?

Calcined alumina micro powder is made from industrial aluminum hydroxide or industrial aluminum oxide as raw materials, and is calcined at appropriate temperatures to form a stable crystal structure α- Type alumina products; To calcine α- Aluminum oxide micro powder is produced by ball milling using type alumina as raw material. It has a high melting point, high mechanical strength, hardness, high electrical resistivity, and thermal conductivity. Calcined alumina micro powder can be applied in industries such as electronic equipment, structural ceramics, refractory materials, grinding materials, polishing materials, etc. Aluminum oxide polishing powder that has been high-temperature calcined α- Al2O3 powder, in addition to containing dispersants, suspensions, lubricants, emulsifiers and other auxiliary components, is used in industries such as thermal conductivity, polishing, electroplating, and catalysts.

1. Calcined alumina micro powder is suitable for shaping products and refractory castables, plastic materials, repair materials, spray repair materials, coatings, binders, high-purity refractory fibers and other amorphous refractory materials. It has a good effect on improving the high-temperature strength and corrosion resistance of refractory materials.

2. Calcined alumina micro powder has the characteristics of high specific gravity, high hardness, good wear resistance, and impact resistance. It is used in machine preparation, optical processing, tableware industry, jewelry processing, automotive parts repair and maintenance, optical lenses, machine electrical accessories, and other industries that require surface treatment, polishing, and grinding.

3. Calcined alumina micro powder is used as a filler for dental cement, porcelain, special ceramics, electronic ceramics, paint, mordant, metallic aluminum, etc. 4. It can be added to water-based resins, oil-based resins, epoxy resins, acrylic resins, polyurethane resins, plastics, and rubbers in an amount of 3% -5%, which can improve the hardness of the material, with a hardness of up to 6-8H.
