Influence of Sintering Process on the Mechanical Properties of Dental Zirconia Ceramics W.U.Park1, J.M.Zhao1, K.H.Hwang1,†, T.
Microwave sintering was very effective in considerable mechanical properties such as flexural strength and bulk density was drastically increased when compared with the conventional electric heating method.
It will be important to seek the accurate sintering condition of dental zirconia by microwave sintering method and continuous research is necessary for the study of the relationship between sintering methods and mechanical properties.
In addition, it lowers the sintering temperature, enhances the physical and mechanical properties, achieves a homogeneous organization, and reduces several risk factors in the work processes.[4] In the field of general dentistry they mainly use the heating and sintering method, but if dental zirconia stays in the furnace at a high sintering temperature for more than eight hours, it takes too much time and increases the cost.
In this study, methods based on microstructure and mechanical properties were evaluated by different sintering methods.
