What is Study on Pb(Zr,Ti)O3–Pb(Zn1/3Nb2/3)O3–Pb(Sn1/3Nb2/3)O3–Pb(Mn1/3Sb2/3)O3 quinary system piezoelectric ceramics about?

In this paper, Pb(Zr,Ti)O 3 -Pb(Zn 1/3 Nb 2/3 )O 3 -Pb(Sn 1/3 Nb 2/3 )O 3 -Pb(Mn 1/3 Sb 2/3 )O 3 (named briefly PZT-PZN-PSN-PMS) quinary system piezoelectric ceramics with various Zr/Ti ratio were prepared by traditional method. The properties of this quinary system piezoelectric ceramics were studied and the effect of Sr 2+ , Ba 2+ doping on dielectric constant ε T r3 and Curie temperature T c were investigated. What's more, the dielectric loss tan δ and dielectric constant ε T r3 under the strong alternating electric (AC) field were discussed. The partial substitution of Pb 2+ with Sr 2+ and Ba 2+ improves ε T r3 and decreases slightly T c . The tan δ and ε T r3 under strong AC fields sharply increase because of the movement and vibration of domain walls resulting from AC field. The good general results are as follows: , tan δ = 0.004 (1 V/mm field), K p = 0.522, T c = 295 • C and the coercive electric field E c = 19 kV cm -1 . When AC field increases to 200 and 400 V/mm, tan δ is equal to 0.013 and 0.041, respectively. The above results were obtained for the certain composition doping 2 mol% Sr 2+ and 2 mol% Ba 2+ .
