Investigation of the thermal expansion and heat capacity of the CaCu3Ti4O12 ceramics
The thermal expansion of the CaCu3Ti4O12 ceramics has been measured over a wide temperature range 120–1200 K. The high quality of the samples under study has been confirmed by good agreement of the results of measurements of the heat capacity in the range 2–300 K and in the vicinity of the phase transi tion of magnetic nature at 25 K with the data for the single crystal. No anomalies in the the...
متن کاملSintering Behavior of 0.8 mol%-CuO-Doped 3Y-TZP Ceramics
In recent years, 3 mol% yttria-stabilized tetragonal zirconia polycrystals (3Y-TZP) doped with copper oxide has obtained increasing interest due to its enhanced superplastisity and good potential in tribological applications. In this work, the effect of addition of small amounts (0.8 mol%) of copper oxide on the sintering behavior of 3Y-TZP was studied using a dilatometer and high-temperature X...
متن کاملPiezoelectric and electrostrictive strain behavior of Ce-doped BaTiO3 ceramics
The ferroelectric and strain behavior of the Ba(Ti12yCey)O3 solid solutions was studied. Three phase transition temperatures were shifted with increasing Ce concentration, and pinched at y 50.06. The samples could be structurally indexed by x-ray diffraction in a tetragonal symmetry at y<0.06; and in a pseudo-cubic symmetry at y.0.06. The strain levels in the range of 0.15–0.19% at ;60 kV/cm wi...
متن کاملHigh Breakdown Field CaCu3Ti4O12 Ceramics: Roles of the Secondary Phase and of Sr Doping
In this work, two methods of CaCu3Ti4O12-CuAl2O4 composite and SrCu3Ti4O12-CaCu3Ti4O12 composite were prepared to improve the breakdown field in CaCu3Ti4O12 ceramics. CaCu3Ti4O12-0.5CuAl2O4 and 0.4SrCu3Ti4O12-0.6CaCu3Ti4O12 samples with proper sintering conditions were found to have greatly enhanced breakdown fields of more than 20 kV·cm−1 compared to the ordinary value of 1–2 kV·cm−1 in CaCu3T...
