The Seebeck coefficient (S) of YBa2Cu3O7-δ 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 ∼ 1130K corresponding to a value of δ = 0.73.
