内容記述(抄録等)The synthesis of thermoelectric materials (β″-alumina) for the alkali metal thermoelectric converter (AMTEC) has been studied using a newly designed plasma jet reactor. Under not only atmospheric pressure but also low pressure, thin films of β″-alumina are successfully synthesized for the first time from powder mixtures of α-Al_2O_3, Na_2CO_3 and MgO. The powder-mixing ratio, jet power and substrate position strongly affect the synthesis of β″-alumina, which is found to be correlated with jet temperature. Synthesis of ferrite particles is also discussed. Under both atmospheric and lower pressures, ferrite particles are successfully synthesized from powder mixtures of Fe_2O_3, ZnO, NiO and CuO. In the high temperature region of the plasma jet, ferrite particles with high purity can be synthesized.
