Alumina is calcined to create Calcined Alumina Powder. Different temperatures are used during the manufacturing process to manage the calcined alumina powder's hardness and abrasive characteristics, including polishing and grinding. Calcined alumina is quickly transformed into pure Aluminum Oxide (Al2O3) at temperatures between 1200 and 1300 oC. Technical ceramics, structural ceramics, polishing agents for metal, plastic, and glass, fillers for rubber and plastics, paint & coatings, refractories, and thermal spray powders are just a few of the industrial applications that calcined alumina is primarily employed in.
Furthermore, owing to unique physical and chemical properties of calcined alumina powder, such as dielectric properties and high melting point, calcined alumina powder is gaining significant popularity in the paint and coatings industry. For instance, according to Coherent Market Insights, the global Paint And Coatings market was valued at US$ 137.25 billion and 46,686.09 kilo tons in 2016, and is expected to expand at a CAGR of 5.6% in terms of revenue and 4.8% in terms of volume during 2017 – 2025.
