| Abstract: | The crystallization behavior of a glass with a composition of 40 wt% 3CaO · P2O5?60 wt% CaO · MgO · 2SiO2 was investigated. The primary crystalline phase was apatite with a dendritic form and ellipsoidal shape. β-(3CaO · P2O5) and CaO · MgO · 2SiO2 were crystallized as samples heated to 990°C, and a three-layer structure was obtained. The development and morphology of this construction were explained by both the surface crystallization of the apatite and CaO · MgO · 2SiO2 and the bulk crystallization of apatite and the CaO · MgO · 2SiO2-β-(3CaO · P2O5) composite. |
