Influence of fabrication processing on phase transition and electrical properties of 0.8Pb(Zr1/2Ti1/2)O3-0.2Pb(Ni 1/3Nb2/3)O3 ceramics
The binary system of 0.8Pb(Zr1/2Ti1/2)O3-0.2Pb(Ni1/3Nb2/3)O3ceramics were synthesized by conventional mixed oxide and columbite method. X-ray diffraction analysis demonstrated the coexistence of both the rhombohedral and tetragonal phases for the columbite prepared sample. Rhombohedral to tetragonal...
