The Crystallization Behaviors of SiO2-Al2O3-CaO-MgO-TiO2
To evaluate the crystallization behavior of Ti-bearing blast furnace slag-based glass ceramics SiO2-Al2O3-CaO-MgO-TiO2 systems with various TiO2 were investigated. The crystallization process and mechanical properties were analyzed. The results show that with TiO2 increasing exothermic peak temperature (Tp) decreases and the crystallization is promoted by the introduction of TiO2.
