【 摘 要 】

This study is designed to prepare and evaluate a new composite material composed of Porcelanite and lithium metasilicate, mixing them in different weight percentages 20:80, 25:75, 40:60, 50:50,and 75:25, respectively, in order to develop a new composite material by a solid state reaction method, with advanced properties for physical and mechanical which can be used for dental veneer applications. Results show that the percentage of Porcelanite strongly enhances these properties for the composite, until reaching the sample with (75% Porcelanite and 25% Lithium meta silicate), which is begun to reduce. The best weight percentage from the view of physical properties, cold crushing strength, and the micro hardness, will be the 50% Porcelanite, which is suggested it to be as a good dental material used in veneer applications.
