| Abstract: | In order to get the whole view on the ferroelectrocity of Pb(Y 1/2 Nb 1/2 )O 3 PbTiO 3 PbZrO 3(PYN PT PZ) ternary ceramics,the initial phase diagram for this system was plotted with referring many other ystems.The new ternary phase diagram of PYN PT PZ ternary system was determined after a large number of detailed experiments.Several compositions of this ternary system were further studied.The resuts show that the piezoelectric and dielectric properties of PYN PT PZ system are very good can be applied well in the future. |
