This Part of EN 725 specifies one fusion and one acid dissolution method for the determination of elements of sodium, potassium, iron, silicon, calcium and magnesium present as impurities in alumina using atomic absorption spectroscopy (AAS) or inductively coupled plasma (ICP) spectroscopy. For each element present as impurities, the methods are applicable to the following ranges, calculated as oxides : - Sodium oxide: 20 ppm to 6000 ppm - Potassium oxide: 20 ppm to 100 ppm - Ferric oxide: 20 ppm to 300 ppm - Silica: 50 ppm to 2000 ppm - Calcium oxide: 20 ppm to 700 ppm - Magnesium oxide: 5 ppm to 1000 ppm
