Electroceramic calcium copper titanates (CaCu 3 Ti 4 O 12, CCTO), with high dielectric
permittivities (ε) of approximately 10 5 and 10 4, respectively, for single crystal and bulk …

The good dielectric and non-ohmic properties of CaCu 3 Ti 4 O 12 and CaCu 2.95 Zn 0.05 Ti
4-x Zr x O 12 (x= 0, 0.05 and 0.10) thin films prepared by a sol-gel method were determined …

Abstract CaCu 3 Ti 4 O 12/CaTiO 3 (CCTO/CTO) composite ceramics were prepared
through in-situ reaction and solid-state sintered at 1040° C for 10 h. The phase composition …

The detection of the toxic H 2 S gas is of great practical, environmental and industrial
interest. This work presents sensing devices fabricated with Ag-doped CaCu 3 Ti 4 O 12 …

Here, we report on the effect of chemical substitution on the structural and optical properties
of Cu-doped CaTiO 3 (CTO) polycrystalline powders synthesized by the polymeric precursor …

Zn-substituted CaCu3Ti4O12 ceramics were prepared by the sol–gel method. Their
microstructures and electrical properties were investigated. XRD patterns showed that the …

Ca 1+ x Cu 3− x Ti 4 O 12 powders were synthesized by a conventional solid‐state reaction.
X‐ray diffraction (XRD) was performed to verify the formation of cubic CaCu 3 Ti 4 O 12 …

NO2 is one of the main greenhouse gases, which is mainly generated by the combustion of
fossil fuels. In addition to its contribution to global warming, this gas is also directly …

We have synthesized single phase Ni+ 2-Co+ 2 substituted bismuth copper titanate (Bi 2/3
Cu 3 Ti 4 O 12) electroceramic using the sol-gel autocombustion method. The XRD patterns …
