ISO 19950:2015
Aluminium oxide primarily used for the production of aluminium — Determination of alpha alumina content — Method using X-ray diffraction net peak areas
ISO 19950:2015 sets out an X-ray diffraction method for the determination of the alpha alumina content of smelter grade alumina. The method is applicable to smelter grade alumina containing alpha phase at levels up to 50 %. The percentage by mass of alpha alumina is determined on an "as received" basis.
