Useful in material polishing and in ceramic materials such as electronic devices, in mechanical parts, whiteware, and fillers for resin.
A key raw material for refractories and abrasives.
In pottery, it is used to increase glaze viscosity, firing range and resistance to crystallisation.
Uses
Aluminium Oxide Calcined is substituted for silica filler in porcelain bodies and is also useful in abrasives, glass, porcelains, spark plugs, and electrical insulators.
Benefits
• Superior mechanical strength and extreme hardness
• Extremely chemically stable
• High electrical insulation and high thermal conductivity
• Resistant to abrasion
Usage Rate
The usage for this product depends on the nature of the formulation, thus there is no exact recommended concentration.
Strengths
Economical option which helps maintain high polishing rates and good surface finish.
Caution
Aluminium Oxide Calcined, commonly known as calcined alumina is the densest and most stable crystalline form of alumina, and is made by roasting a source alumina powder at 1200-1300ºc. This makes it possible to control the hardness and abrasive properties of the alumina, such as polishing and grinding. It is useful in many industrial applications such as structural and technical ceramics, polishing compounds for plastic, metal, and glass, fillers for rubber and plastics, anti slip, refractories, paint and coatings, and thermal spray powders. This white crystalline powder is chemically stable and has a high melting temperature (about 2000ºc). Calcined alumina is odourless and insoluble in water. It is used in a variety of ceramic and refractory applications.
