Abstract:	The polymorphism of Li₄SiO₄, Li₄GeO₄ and Li₄TiO₄ has been studied. All three phases are isostructural above 700–750°C, but undergo phase transformations on cooling. At lower temperatures only Li₄GeO₄ and Li₄TiO₄ are isostructural. Subsolidus phase equilibria within the system Li₄SiO₄Li₄GeO₄Li₄TiO₄ have been investigated.
