Abstract
The Seebeck coefficient (S) of $YBa_2Cu_3O_{7-\delta}$ was measured in the temperature range 450 – 1200 K in air and in pure oxygen in order to derive information on charge carrier concentration. The orthorhombic to tetragonal phase transition manifests as maxima in the variation of (dS/dT) with temperature. Seebeck coefficient in air decreases beyond $\sim 1130K$ corresponding to a value of $\delta=0.73$.
