Alumina, alumina powder, or aluminium oxide is a compound used in production of aluminum, a metal widely applied throughout industries. However, the scope of its application encompasses a number of other fields including advanced ceramic manufacturing companies. Due to numerous favorable properties of aluminium oxide, it is one of the most prevalent materials across multiple industries. Understanding alumina’s application scope and main properties behind it can benefit your manufacturing process in many ways.

High pressure resistance, thermal resistance, and excellent hardness, are the main properties of alumina that allow for its wide application scope. This makes various parts and components made from aluminium oxide a welcome addition across a wide range of industries that require precision, complex designs, and favorable physical and chemical characteristics.

Protective and military equipment

Due to its lightweight qualities and exceptional strength, alumina is often usedt in the production of civilian and military protective equipment. Aircraft armor industry is one of the largest consumers of aluminium oxide, while other applications include the manufacturing of vehicle armor, body armor, ballistics for stationary objects and bulletproof windows.


Aluminum powder is a crucial component in the production of microchips and other electronic equipment, featuring excellent thermal resistance, as well as a high boiling and melting point. It is also widely used in heat sink insulation. Due to its high conductivity, it’s mainly implemented in creating conductive pathways in electrical devices such as solar cells and light-emitting diodes. 

Gem industry 

Corundum is the crystalline form of alumina powder and it’s the base element of sapphires, rubies, emeralds, and other precious gems, depending on trace levels of contaminants such as chromium, iron, and titanium. Due to its excellent hardness, it’s used for polishing gems, including the most difficult ones with level 8 hardness.

Construction materials

Alumina is a chemically inert compound with high abrasion resistance, making it an ideal filler for bricks, plastics, and heavy clayware including kilns. It is also used as sandpaper in a wide range of construction-related applications. Aluminium oxide nanofibers are used to design cement-based composites of ultra high strength. 

Wide industrial applications

Aluminium oxide can be used in a broad range of industrial applications from hydro cyclones to reducers, valves, nozzles, and piping components such as straight pipes, elbows, and tees. It is suitable for use in the production of cutting tools, machining tools, wear-resistant pump impellers, and thermocouple sheaths.


Alumina can catalyze a range of reactions used industrially. It is most common as a catalyst in refineries, in the Claus process, converting waste gasses of hydrogen sulfide into elemental sulfur, as well as to dehydrate alcohols to alkenes. 

Aluminium oxide is also a frequent supporting compound for industrial catalysts, including Ziegler-Natta polymerizations and catalysts applied in hydrodesulfurization.
