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

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

The emissivity factors of Co 2 O 3 , NiO, and Fe 2 O 3 are studied in the temperature range 293–1100 K. The application of Co 2 O 3 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....

The application of Co 2 O 3 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.
