| Description |
By means of complex independent methods the processes occurring at preparation of Ca3Co4O9+ ceram-ics using solid-state reactions and different solution (citrate, polymeric and sol-gel) methods were investi-gated. The crystal structure and microstructure, oxygen stoichiometry, thermal expansion, electrical con-ductivity and thermo-EMF of the samples were studied and values of their power factor were calculated. It is shown that usage of solution methods let us obtain more dense and fine-grained ceramics, which is char-acterized with higher values of electrical conductivity and power factor.
