    The effects of Al<sub>2</sub>O<sub>3</sub> on the crystallization behavior of glass compositions in the Na<sub>2</sub>O-CaO-SiO<sub>2</sub> system were investigated by differential thermal analysis (DTA), X-ray diffraction (XRD) and scanning electron microscopy (SEM). Effect of Al2O3 content on the mechanical, density, phase formation and microstructures of Na<sub>2</sub>O-CaO–P<sub>2</sub>O<sub>5</sub>–Al<sub>2</sub>O<sub>3</sub>-SiO<sub>2</sub> glass ceramics were studied. Thermal parameters of each glass were studied by DTA. The density of the glass ceramic samples was measured by Archimedes’ method. It was found that the glass–ceramic containing 2.0 molar percent Al<sub>2</sub>O<sub>3</sub> had desirable sintering behavior and reached to an acceptable density. Phase investigation and micro structural study were performed by XRD and SEM, respectively.
