Govt. P.G. College, Gyanpur, Bhadohi (INDIA) <p style="text-align: justify;">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 O^2-: 2p and M³⁺ : 4s bands as valence and conduction band. Energy band gap and mobility of the charge carriers have also been evaluated.</p> <p style="text-align: justify;">&nbsp;</p> <p style="text-align: justify;">&nbsp;</p> https://ultraphysicalsciences.org/paper/1178/ Electrical conductivity Seebeck coefficient Zirconates Conduction mechanism mobility.
