제목 Bioactivity, Crystallization and Sintering Behavior of CaO-SiO2-P2O5 Bioglass-Ceramics with the Addition of ZnO
초록 In the bioactive glass-ceramics containing wollastonite and fluorapatite of the CaO-SiO2-P2O5 system, different amounts of ZnO were added and the crystallization behavior, sintering behavior and bioactivity characteristics of the glass were examined. The nucleation and crystallization behavior of bioactive glass-ceramics samples was determined by differential thermal analysis (DTA). The formed crystalline phases were identified using X-ray diffraction investigation. Complete surface analyses were performed utilizing scanning electron microscopy.  

It was found that in ZnO containing samples, the sinterability, crystallization and chemical resistance were improved by increasing of ZnO amount. The glass transition temperatures, crystallization temperatures, and optimum sintering temperatures decreased as the amount of ZnO increased. The chemical resistance and bioactivity of the glasses were also examined and explained in correlation with the crystallization and densification.
