Fabrication of hydroxyapatite glass-ceramic by adding ZrO2 for dental application

Abstract

The aim of this work was to fabrication of Hydroxyapatite Glass-ceramic by adding ZrO2 for Dental Application. The glasses were prepared by conventional melting of the coprecipitation derived starting products and heat treated at different temperatures. The structure mechanical properties and microstructure of the samples were characterized by X-ray diffraction, Vicker hardness, energy dispersive X-ray analysis (EDXA) and scanning electron microscopy. The data showed that the samples with condition Li1-1450 and heated treatment at 830 C having high strength and proper crystallinity showed good translucency, which comparable with that of the sample from factory. XRD analysis revealed XRD analysis revealed that the peak corresponds to the crystallization of Li2SiO3, SiO2or Li6SiO8which are important phases have effect to increasing the mechanical properties of samples.
