Alumines Durmax

Experts in aluminium oxide and hydroxide

Since 1928, Alumines Durmax has led the way in the manufacturing of aluminum oxide and aluminum hydroxide, calcined alumina and hydrated alumina, metallographic aluminas, flame retardants, flame-retardant fillers, special fillers for synthetic resins as well as corundum, aluminas for special ceramics, and high-purity calcium fluoride.

The different designations of alumina

Alumina is also known as alumina oxide, calcined alumina, activated alumina, hydrated alumina, alumina hydrate, alumina hydroxide, aluminum hydroxide, corundum and calcium fluoride. Regardless of the name, the formula remains the same: Al2O3. The only difference is in how the product is manufactured.

What is the Bayer process ?

For the extraction of the aluminum oxide (Al2O3), also called alumina, contained in bauxite, we use the Bayer process, an industrial process suited to the production of alumina. This technique facilitates the extraction of aluminum oxide by using high pressure and temperature to dissolve the gibbsite/boehmite contained in the bauxite. The process entails 5 steps and results in a white power known as alumina.
