• The glass-forming regions in the Li<SUB>2</SUB>O–TiO<SUB>2</SUB>–P<SUB>2</SUB>O<SUB>5</SUB>, MgO–TiO<SUB>2</SUB>–P<SUB>2</SUB>O<SUB>5</SUB>, and CaO–TiO<SUB>2</SUB>–P<SUB>2</SUB>O<SUB>5</SUB> systems have been determined. Homogeneous glasses were formed with compositions of less than 50 mol% P<SUB>2</SUB>O<SUB>5</SUB> in all three systems. The largest quantities of TiO<SUB>2</SUB> could be introduced into glass for compositions of 30 mol% P<SUB>2</SUB>O<SUB>5</SUB>. In compositions with more than 50 mol% P<SUB>2</SUB>O<SUB>5</SUB> only a mixture of the glass and crystal was formed. With an increase in the TiO<SUB>2</SUB> content, the density of the glass increased and the volume per mole of oxygen decreased. These results indicate that the TiO<SUB>2</SUB> had been easily incorporated into the glass with compositions of lower P<SUB>2</SUB>O<SUB>5</SUB> contents, contributing to the stabilization of the glass structure.
