A novel ceramic cemented carbide compact insert was developed using hot pressing sintering technique. The surface layers of the sandwich material were ceramic and the middle layer was cemented carbide. The factors that affect the properties of the compact insert were analyzed. Theoretical analyses and experiments indicated that the cemented carbide with greater elastic module and thermal expansion coefficient than ceramic should be used in the sandwich material in order to get high equivalent flexure strength and the geometric parameters of the compact insert are also important to its properties.
