The calcination of alumina results in the production of Calcined Alumina Powder. The manufacturing process takes place at various temperatures, which control the hardness and abrasive properties of calcined alumina, as well as polishing and grinding. Calcined alumina is easily converted into pure Aluminum Oxide at temperatures ranging from 1200 to 1300oC. (Al2O3). Calcined alumina is primarily used in technical ceramics, structural ceramics, polishing compounds for metal, plastic, and glass, fillers for rubber and plastics, paints and coatings, refractories, and thermal spray powders.

Ceramics accounted for a significant market share among applications in 2016. The ceramics industry includes a wide range of applications such as advanced ceramics, technical ceramics, honeycomb ceramics, spark plugs, high voltage insulators, and wear parts. Key factors such as rising demand for paint and coatings globally are expected to drive growth in the Global Calcined Alumina Powder Market during the forecast period. Because of its robust mechanical, electrical, thermal, and chemical properties such as hardness, dielectric properties, and high melting point, calcined alumina is a commonly used raw material in almost every ceramic application.

Furthermore, Calcined Alumina Powder is gaining popularity in the paint and coatings industry due to its unique physical and chemical properties, such as dielectric properties and a high melting point. These characteristics make calcined alumina an important product in applications such as the production of ceramic shapes, refractories, and abrasives. Calcined alumina is also used in polishing compounds, anti-slip fillers, paints and coatings, and thermal spray powders.

Calcined Alumina, also known as aluminum oxide, is made by continuously calcining alumina at different temperatures. The final product's properties can be controlled by adjusting the calcination temperatures. Calcined Alumina Powder does not lose weight when fired and is harder than tungsten carbide or zircon. Calcined alumina can withstand high temperatures and has explicit properties such as high mechanical strength and hardness, refractoriness, electrical insulation, and resistance to wear, abrasion, chemical attack, and corrosion.
