N2 - Temperature measurement in plasma-surface interaction studies is an important task. Pyrometry is widely used for these purposes. This study evaluates the accuracy of a two-color pyrometer developed to investigate thermal shock effects in high-temperature ceramics – promising plasma-facing materials of fusion devices. Based on emissivity data of such ceramic materials as boron carbide (B4C), silicon carbide (SiC) and zirconium diboride (ZrB2), calculations showed the possibility of using this method to measure temperatures in the range of 1200–2000 K. Experimental temperature measurements during the pulsed heating of the specified ceramics showed that the deviations of single color temperatures from two-color ones were less than 5%, which demonstrates the suitability of the two-color method for measuring the surface temperatures of these materials.
