Abstract:
1. Apatite glass ceramic comprising at least one glass phase and at least one apatite phase, wherein at least one apatite phase is a phosphate- and fluorine-free siliceous oxyapatite phase, which contains one or more oxyapatite phases of the formula Me[I] x Me[II] y Me[III] z (SiO 4 ) 6 O 2 , in which Me[I] represents a monovalent cation, Me[II] a divalent cation and Me[III] a trivalent cation and x, y and z are chosen so that the sum of the valences of the cations Me[I], Me[II] and Me[III] gives the value 28.
