Abstract

The nature of the titanium-containing phases which crystallize from solutions of TiO2 in fused alkali metal borates, varies with the alkali cation, the mole ratio of alkali oxide to B2O3, and the initial concentration of TiO2. Recrystallization of TiO2 rather than crystallization of complex titanates, is enhanced by the presence in solution of small cations, by a high proportion of B2O3 relative to alkali oxide, and by higher concentrations of TiO2.

The crystallization of complex titanates is correlated with the formation of borate groups containing non-bridging oxygens whose existence has been suggested by previous workers.
