Pseudobinary Phase Relations of Li2Ti3O7

The Li2O‐TiO2 pseudobinary phase diagram was determined from 50 to 100 mol% TiO2 by DTA, microscopy, and X‐ray analysis; Li2Ti3O7 effectively melts congruently at 1300° and decomposes eutectoidally at 940°C. A solid solution based on Li2TlO3 from 50 to ∼65 mol% TiO3 was observed to exist at >930°...

Description
Summary:The Li2O‐TiO2 pseudobinary phase diagram was determined from 50 to 100 mol% TiO2 by DTA, microscopy, and X‐ray analysis; Li2Ti3O7 effectively melts congruently at 1300° and decomposes eutectoidally at 940°C. A solid solution based on Li2TlO3 from 50 to ∼65 mol% TiO3 was observed to exist at >930°C. A new metastable phase was discovered with a composition of ∼75 mol% TiO2 and with a hexagonal unit cell (8.78 by 69.86 × 10−1nm). Discrepancies in the literature regarding some of these phase equilibria are reconciled.
