摘要：
In this work, phase separation, nucleation and crystallization of the glass in the system K2O-MgO-Al2O3-B2O3-SiO2-CaO-P2O5-F were observed and analysed. Glass ceramics with two main crystalline phases were prepared by selecting suitable glass compositions and program of heat treatment. The multiple phase separation of the parent glasses can play an important role in nucleation and crystallization. XRD analysis indicated that the two main cryatlline phases were fluorapatite and fluorophlogopite, which are very important for bioactivity and applicability. This glass ceramic is considered as a very promising biomaterial.
