Investigation of thermoradiation properties of carbides of refractory metals at high temperatures by pulse electrical heating

Experimental study of thermoradiation properties of refractory metal carbides by the pulse heating method was performed. Quasi-stationary emission spectra of the eutectic system MoC0.82 at high temperatures are obtained, the normal spectral emissivity of this carbide material at two wavelengths is calculated. The efficiency of the chosen technique of spectral pyrometry for studying the thermoradiation properties of refractory carbides at high temperatures is demonstrated.
