ABSTRACT:

The electrical conductivity (s) and Seebeck coefficient (S) of trivalent Fe and Co zirconates were measured in the temperature range 500-1200K. The studied zirconates, Fe and Co, under go a phase transition at 780K and 760K respectively. The results have been explained on the basis of a energy band diagram. It has been concluded that conduction mechanism in these solids is intrinsic band type with O2– : 2p and M3+ : 4s bands as valence and conduction band.
