Abstract :
The fabrication of β"-alumina films, as a thermoelectric material, by thermal plasma processing based on the forced constrictive type reactor was investigated. Under both atmospheric and low pressure, β"-alumina films were successfully synthesized from mixed powder of α-Al2O3, Na2CO3 and MgO. The jet power and substrate position strongly affect the properties of plasma processed β"-alumina, which was found to be correlated with jet temperature. For both pressures, the films show good thermoelectric properties
