Thermoelectric materials (β″-alumina) for the alkali metal thermoelectric converter (AMTEC) have been synthesized with the use of a thermal plasma reactor based on the forced constricted type plasma jet generator. It is reconfirmed that the powder mixing ratio (i.e. the ratio between α-Al_2O_3, Na_2CO_3 and MgO), jet power and substrate position, strongly affect the synthesis of β″-alumina. Besides these, the synthesis of β″-alumina is also enhanced in the high-temperature region by oxygen injection. Those dependences are correlated with jet temperature and particle heating. The metal electrode of molybdenum is also prepared by spraying Mo powders. Porosity of the prepared films could be well controlled by varying the pressure.
