Describes a gravimetric method for determining the loss on ignition and the classical and spectrophotometric methods of analysis of high alumina refractory materials for the determination of the oxides of silicon, phosphorus, aluminium, iron(III), titanium, manganese, calcium and magnesium. Sodium, potassium and lithium are determined as the oxides by flame photometry. The results are expressed as a percentage (m/m) of the original material. The typical composition of high alumina refractory materials, is included together with a statement on the repeatability of the analysis.
