適用范圍：1.1 This standard prescribes methods for chemical analysis of various grades of minerals like limestone, dolomite, calcite and magnesite, the average composition of which is given under 1.2. This standard also covers the methods for magnesite refractories. Separate methods for this purpose have been included wherever necessary.1.2 * CompositionPercentLoss on ignition 40 to 50Silica (SiO2) 0.2 ? 4Alumina ( Al2O3 ) 0.2 ? 2Iron oxide ( Fe2O3 ) 0.2 ? 2Calcium oxide ( CaO ) 0.5 ? 55Magnesia ( MgO ) 0.5 ? 52Carbon dioxide ( CO2 ) 42 ? 52
