Abstract:

This paper reports results of electrical conductivity (s) and Seebeck coefficient (S) measurements on the pressed pellets of V2ZrO5 and Mn2ZrO5 in the temperature range 500 - 1200 K. It has been found that these compounds are almost insulators. In general log sT vs T-1 as well as S vs T-1 plots yield two linear temperature regions. The sign of S indicates the charge carriers are electrons in the studied temperature range. The studied zirconates undergo a phase transition at 810 K and 785 K respectively. The conduction mechanism in these solids in intrinsic band type with O2-: 2p and M3+ : 4s bands as valence and conduction band. Energy band gap and mobility of the charge carriers have also been evaluated.
