Aluminium Oxide – Alumina

Alumina is anhydrous aluminium oxide with a crystalline structure obtained by calcining aluminium hydroxide at temperatures over 1000° C. During calcination, hydroxide loses bound moisture. The size of the alumina particles remains between 75 and 95µm. Company Alumina offers several types of low-calcined alumina: Smelter grade, Non-metallurgical (Chemical grade), Low soda grade and White alumina.

This material has a wide commercial application. It is used as raw material in the production od metal aluminium (smelters), in the production of refractory materials, steel industry, in the production of glass, production of corundum, production of special grade aluminas, as well as aluminium and magnesium spinels, production of catalyst, production of abrasives, ceramic industry etc.
