Some Thermal Properties of Tantalum

Measurements have been made on the total radiation from very pure, well seasoned tantalum from 1000°K to 2220°K. A spectral temperature scale, $\lambda =0.667\mathrm{}$μ, is given up to 2100°K. The variation of the resistance of tantalum has been measured up to 2600°K and the thermoelectric power of tantalum with pure platinum has been measured up to 692°K.
