Influence of processing conditions on the morphotropic phase boundaries and ferroelectric properties of Pb(Zn1/3Nb2/3)O 3-Pb(Ni1/3Nb2/3)O3Pb(Zr 1/2Ti1/2)O3 solid solutions
Ceramic solid solutions within the ternary system of Pb(Zn 1/3Nb2/3)O3 - Pb(Ni1/3Nb 2/3)O3 - Pb(Zr1/2Ti1/2)O3 (PZN-PNN-PZT) were synthesized via two methods: the mixed oxide method and the columbite method. Phase development of the calcined powders and the crystal structure of sintered ceramics were...
