Titre: Effect of phosphorus pentoxide addition on the microstructure Auteur(s): Hamzioui, L.; Boutarfaia, A.; Kahoul, F. Résumé: We can note that the sintering temperature of the piezoelectric Pb0.98Ca0.02[(Zr0.52Ti0.48)0.98 (Cr 3+ 0.5, Ta 5+ 0.5)0.02]O 3 can be reduced after the addition of phosphor without compromising the dielectric properties. A sintered density of 96 % of the theoretical density was obtained for 4 wt. % P2O5addition after sintering at 1050 °C for 2 h. Ceramics sintered at 1050 °C with 4 wt. % P2O5achieve excellent properties, which are as follows: εr = 18808, tan δ = 0.0094 and Tc = 390°C.
