The Fabrication of lithium disilicate glass ceramic for dental application

Abstract

The purpose of this project is analyze to the transparency and mechanical properties of lithium disilicate for dental application. Lithium disilicate glass-ceramic were synthesised by using melting technique in SiO2-Li2O-Al2O3-K2O -P2O5 glass system and heated treatment samples at the crystallization temperature of that glass. The Differential thermal analysis: DTA, X-ray diffraction: XRD were used analysis on thermal properties phase formation. Moreoven density, Hardness were determined to evaluate the properties at physical and Mechanical respective by the X-ray diffraction showed that the glass-ceramic sample demonstrated the phase of Li2SiO3, Li2Si2O5 and SiO2 . The optimum of glass-ceramic. Sample were on faired with the sample heated 650°c first step and heated at 800°c for second step. That show the highest hardness valve at 755 HV
