Abstract
A perovskite-like CaV1-xMoxO3-δ (x = 0.2 ÷ 0.6) were prepared by a formate solution method with the final annealing at 1473 K in an H2 atmosphere. X-ray diffraction analysis was used for sample characterisation. Metal-like electric conductivity was observed using a 4-probe DC technique from 573 to 1123 K in dry H2. Magnetic susceptibility measurements showed the absence of localised V and Mo valence electrons. The Seebeck coefficient was measured between temperatures of 573–1123 K in dry H2, supporting the hypothesis that electronic conductivity is predominant. Thermal expansion coefficients (TEC) are obtained by dilatometry from 373 to 1123 K in dry H2. TEC values increase with temperature from 10 ppm to 15 ppm K−1 and decrease with Mo concentration.
