Development of the Compositions of High-Temperature Coatings with a High Emissivity Factor to Intensify Radiant Heat Exchange

Resumo

The emissivity factors of Co₂O₃, NiO, and Fe₂O₃ are studied in the temperature range 293–1100 K. The application of Co₂O₃ and NiO in coatings is shown to increase the emissivity factor of a heat-exchange surface in the wavelength range λ = 0.75–12.0 μm and the given temperature range.
