Apatite and mica-containing glass-ceramics in the system K20-Mg0-Ca0-Al203-B203 Si02-P205-F can be used to repair and reconstruct diseased or damaged bones and teeth, due to their biocompatibility and bioactivity. Like other glass-ceramics, the properties of these machinable glass-ceramics depend on composition, size and volumetric ratios of the crystalline phases in the materials. Phase separation, nucleation and crystallisation of these multi-phase glass-ceramics were investigated with DTA, SEM/EDAX. XRD and FTIR techniques. The phase relationships are discussed with regard to crystal chemistry, thermodynamics and kinetics.
