Microstructure and mechanical properties of dental 3Y-TZP ceramics by using CaO-P2O5 glass as additive

The results of the experiment showed that these glass frit additives neither destroy the stability of the high temperature t-phase nor induce grain growth. All the mechanical properties and the relative densities were strongly correlated with the addition of glass frits. At lower sintering temperatures, the presence of glass additives resulted in an increase in mechanical properties. At higher sintering temperatures, the presence of glass additives decreased the mechanical properties.
