Abstract

The development of a direct-reading spectrometric method for the determination of Al₂O₃, CaO, Fe₂O₃, TiO₂, MgO and Mn₂O₃ in high silica (>92 per cent SiO₂) is described. Once the effect of silica on the spectral intensities has been evaluated it has proved possible to 'set up' the instrument on silica-free standards without loss of accuracy. The results for Al₂O₃, TiO₂, MgO and Mn₂O₁ are at least as accurate as existing chemical procedures; the results for CaO and Fe₂O₃ are of routine control level
