Abstract
A machineable glass ceramic that also has other good characteristics, such as hardness, chemical durability and biocompatibility, is formed from a batch mix having the composition range (in mole %): Al2O3: 1.5 to 15.0; CaO: 22.0 to 55.0; P2O5: 28.0 to 65.0; SiO2 (and/or B2O3): up to 15.0; TiO2 (and/or ZrO2): up to 10.0. Up to 15 mole % may be added of any one or more of Na2O, K2O, Li2O, MgO, BaO and ZnO, to aid melting of the glass. Specific manufacturing stages and two specific batch mixes are given, and a wide range of uses is suggested.
