Crystal Phase Formation and Mechanical Properties of Lithium Disilicate Glass-ceramics for Dental Restoration

摘要：

The purpose of this study was to evaluate the crystal phase formation behavior and its influence on the mechanical properlies of LiO2-SiO2-P2O5 glassceramics system. High temperature XRD was used to analyze the crystal phase formation in situ. The crystalline phases in the material both before and after heat-treatment were also analyzed. The flexural strength was measured by three-point bending test according to ISO 6872:2008(E). The SEM analysis showed that the high strength of the glass-ceramics is attributed to the continuous interlocking microstructure with fine lithium disilicate crystallines.
