Synthesis and Dielectric and Ferroelectric Properties of Ceramics in (1-x)Pb(Zr1/2Ti1/2)O3–(x)Pb(Co1/3Nb2/3)O3 System

“…At higher PCN contents, they then drop to P r ¼ 14:5 mC/cm 2 and P s ¼ 15:2 mC/cm 2 in 0.5PZT-0.5PCN. However, it should be noted that the P r (2.9 mC/ cm 2 ) for the composition x ¼ 0:1 in the present work is lower than the P r ($15 mC/cm 2 ) in a previous study, 20) probably due to the fact that the solid-state conventional mixed oxide method used in the previous study 20) yielded two MPB compositions at x ¼ 0:1 and 0.5, which is different from the columbite-wolframite method used in this study, which showed only one MPB composition at approximately 0:2 x 0:3. It is well known that ferroelectric values, such as P r , P s , and E c , show maximum values approximately at the MPB composition.…”

“…The XRD patterns of the PZT-PCN compositions show a range in symmetry between the tetragonal and pseudo cubic perovskite types. 20) For a better comparison, ICDD file no. 04-002-0416 for Pb(Co 1=3 Nb 2=3 )O 3 with pseudo cubic structural symmetry is also displayed in Fig.…”

Estimation of Total Polarization and Thermal Expansion Behavior in PZT-PCN Ceramics

“…Dense perovskite-phase (1−x)Pb(Zr 1/2 Ti 1/2 )O 3 -(x)Pb(Co 1/3 Nb 2/3 )O 3 (x = 0.1, 0.3 and 0.5) ceramics with uniform microstructure and high density values were prepared from PbO, columbite CoNb 2 O 6 , and wolframite ZrTiO 4 powders by the mixed-oxide method [18][19][20]. Details of ceramic processing and characterizations have already been reported elsewhere [7,8].…”

Changes in the dielectric properties of Pb(Zr1/2Ti1/2)O3–Pb(Co1/3Nb2/3)O3ceramics under compressive stress applied perpendicularly to the electric field

“…) ceramics with uniform microstructure and high density values were prepared from PbO, columbite CoNb 2 O 6 , and wolframite ZrTiO 4 powders by the mixed-oxide method [7,8,23]. Details of ceramic processing and characterizations have already been provided elsewhere [7,8].…”
