Influence of Reaction-Sintering and Calcination
during calcination caused deterioration of electrical conductivity. Phase composition and Seebeck coefficient of sin-tered calcium manganate were not influenced by the calcination procedure. The highest thermoelectric properties with the highest power factors and figures of merit were obtained by means of reaction-sintering of uncalcined pow-der.
