On the Chemistry of Bauxite Extraction. III. Studies in the System Na₂O? MgO? CaO? Al₂O₃? TiO₂? H₂O The formation of crystalline compounds in the system Na₂O? MgO? CaO? Al₂O₃? TiO₂? H₂O was studied at 100°C and atmospheric pressure. Magnesium titanates or magnesium aluminates were not detected in the investigated range of concentrations. In the presence of Ca(OH)₂ the same compounds are formed as in the system Na₂O? CaO? Al₂O₃? TiO₂? H₂O. In addition, sodium aluminates are formed at high sodium and aluminium concentrations.
