Abstract
Carbon, carbides, and nitrides are materials having a relatively high emissivity over the entire spectral range. They are important both as a material and as material components of composites for high-temperature applications, e.g.. in space technology (reusable space transport systems) or energy systems (hot gas turbines). The normal total and spectral emissivities of these three materials have been investigated in the temperature range 1000 to 2000 K and at wavelengths between 0.6 and 6.8 μm. The results have been used to interpret emissivity results of fiber-matrix composites. They are also discussed with regard to potential application as reference materials for high-temperature emissivity measurements.
