Calcium phosphate invert glasses, which contain P2O72- and PO43- ions, have been prepared via the addition of a small amount of TiO2. The formation of bonelike calcium phosphate apatite on the surface of the phosphate invert glasses was examined in simulated body fluid (SBF) at a temperature of 37 °C. Soaking for 20 d resulted in the deposition of leaflike apatite particles on 6CaO·3P2O5·TiO2 invert glass (based on molar ratio). The glass had much-greater chemical durability against SBF, in comparison with a metaphosphate glass; P ions were not dissolved excessively from the 6CaO·3P2O5·TiO2 glass, so the apatite formation was not suppressed.
