A Calibrations

Gives the procedures for the measurement of loss on ignition and of silica, ferric oxide, titania, manganese oxide, chromic oxide, alumina, lime and magnesia in magnesites and dolomites and of alkali metal oxides in magnesites, suitable for industrial refractories. The methods are generally not sufficiently sensitive for the analysis of special high-purity magnesias.
