Outline of Final Research Achievements

Thermoelecric propeties of new compound Na-B-Si were studied to develop a high-temperature thermoelectric material. The bulk ceramic of Na-B-Si was obtained by heating a boron compact in sodium-silicon solution at 900℃. The thermoelectric properties of the sample increased with increasing temperature.
