A method for the chemical analysis of chrome ores and chrome-bearing refractories

Abstract

This paper includes a detailed description of a method for the analysis of chrome ores and chrome-bearing materials; it is to be submitted to the British Standards Institution for acceptance as a standard method. The determinations include those of SiO₂, TiO₂, Al₂O₃, Fe₂O₃, CaO, MgO, Cr₂O₃, MnO, alkali-metal oxides and loss on ignition. The experimental work leading to the final method is described and tables of co-operative results obtained by the Refractories Working Group of the Analysis Committee of the British Ceramic Research Association are included.
