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.

Our products

We create a huge selection of aluminum oxides, aluminum hydroxides, hollow alumina macrospheres and calcium fluorides, and can also concoct formulas designed to your specific and exacting needs. Take a look at our catalog for more information on our manufacturing process.

With over 200 unique aluminas available, not everything is listed in our catalog. If you need a specific formula, a unique creation, or you want to adapt an existing formulation, just contact us for more information.

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.

OUR AREAS OF ACTIVITY

Our aluminas can be used in the following fields:

  • automotive industry,
  • aeronautics,
  • catalyst,
  • ceramics,
  • electronic,
  • horology,
