In this research, sinterability, mechanical properties and microstructure of two different glass- ceramics belonging to CPNT (CaO-P2O5-Na2O-TiO2) and CPMSF (CaO-P2O5-MgO-SiO2-F) as well as their composite were monitored. To this purpose, CPNT:CPMSF composite with 40:60 weight ratio obtained by sintering the mixture of glass powders of base systems. Sinterability and crystallization behavior of the initial system glasses and composite were analyzed by means of differential thermal analysis (DTA) and X-ray diffraction (XRD). Evaluating the mechanical properties of dense and sintered specimens revealed that the Vickers Microhardness and Bending Strength of the composite specimen has been improved relative to the primary glass-ceramics. Furthermore, the composite specimen showed moderate machinability behavior without any fracture. Microstructure of specimens were analyzed by Scanning Electron Microscopy (SEM).
