Influence of processing conditions on the phase transition and ferroelectric properties of Pb(Zn1/3Nb2/3)O 3-Pb(Zr1/2Ti1/2)O3 ceramics

Ceramics solid solutions within the binary system of xPb(Zn 1/3Nb2/3)O3-(1-x)Pb(Zr1/2Ti 1/2)O3 with x=0.1-0.5 were synthesized via the mixed oxide method and the columbite method. Phase development of calcined powders and the crystal structure of sintered ceramics were analyzed by X-ray diffraction....
