Effect of TiO2 on the Mechanical Properties of the K2O-MgO-SiO2-CaF2 Glass-Ceramics

The nucleating effect of TiO2 on the K2O-MgO-SiO2-CaF2 glass ceramics is studied from the point view of the mechanical properties. It is concluded that TiO2 is an effective nucleating agent, and its appropriate amount in the glass is 3 mol%. Furthermore the effect of the mixed nucleating agent of TiO2 and Y2O3 on the mechanical properties of the glass-ceramics is also studied. The mechanical properties of the glass ceramics are all related to their microstructure.
