Synthesis, structure and properties of the solid solutions based on layered calcium cobaltite
Abstract
The (Ca,M)3Co4O9+δ (M = Na, Cu, Pb, Bi) solid solutions have been synthesized, their lattice constants have been determined and their electric conductivity and thermo-EMF were studied in 300-1100 K temperature interval. It has been found that Ca2,8Pb0,2Co4O9+δ solid solution possessed the greatest thermo-EMF coefficient of 0,32 mV/K at 1100 K. Activation energies of electrical conductivity and power factor of ceramics studied have been calculated.
