Y heavy doped (Sr, Y)TiOx was fabricated by plasma spray technique and its thermoelectric properties were evaluated. Y was successfully replaced Sr up to 25% and a uniform solid solution was made. The increase in Y content produced the increase in the electric conductivity and the decrease in the thermal conductivity. But Seebeck coefficient also decreased with increasing Y content. As a result, ZT value did not exceed 0.1 at any Y content. However, it was demonstrated that a plasma spray technique worked well for over dosing an additive element.
