Effect of thermal treatment on dielectric properties of 0.8Pb(Zr 1/2Ti1/2)O3 - 0.2Pb(Co1/3Nb 2/3)O3 ceramics
A combination between piezoelectric (Pb(Zr1/2Ti 1/2)O3; PZT) and relaxor ferroelectric (Pb(Co 1/3Nb2/3)O3; PCN) materials with a formula of 0.8Pb(Zr1/2Ti1/2)O3 - 0.2Pb(Co 1/3Nb2/3)O3 has been prepared with solid-state reaction (the columbite-wolframite precursor method). This specific composition wa...
