Description
In this work, glass and glass-ceramics of the 3CaO.P2O5-SiO2-MgO system were developed aiming to produce different crystallization degrees. Glasses were melted at 1600 deg C and heat treated at 700 deg C. Part of the glasses was crystallized using heat treatments at 770 deg C and 1150 deg C for 4h. The partial crystallization and phase transformations were responsible for different mechanical properties (bending strength, young modulus, fracture toughness and hardness) in each temperature. The mechanical response of the material is discussed in relation to the microstructure, crystalline phases, and porosity of the materials. (author)
