Silicate bioglass-ceramics with incorporation of small TiO2 and MgO were prepared using an appropriate two-step heat treatment for controlled crystallization defined by differential thermal analysis (DTA). Identification and quantification of crystalline phases precipitated from the silicate glasses were done by X-ray diffraction. X-ray diffraction patterns of the samples showed the presence of sodium calcium silicate as the main crystalline phase. The evolution of the XRD peaks with the addition of MgO and TiO2 showed the formation of a new crystalline calcium phosphate phase.
