Radiation cooling for heat sinks with high emissivity lanthanum aluminate ceramic coating

Effect of TiO2 on the thermal performance and emissivity of glass coatings

“…The temperature reduction was attributed to the doped graphene which increased the emissivity of the surface of the aluminium substrate, thus improving the thermal performance. Wang (2023) et al 7 indicated that applying a coating with an emissivity of 0.91 to steel plates could reduce their temperature by 8 °C. Leivo (2001) et al 8 observed the morphology of polyamide powder coatings with Al 2 O 3 as the main filler and found that the effective homogeneous distribution of thermally conductive materials in the coatings not only improves the mechanical properties of the coatings, but also continuously enhances their thermal conductivity.…”

Feasibility research of perovskite‐type PrAlO3+δ as high‐temperature infrared radiation coating

“…The deliberate manipulation of the inner electronic structure and the degree of lattice distortion within LaAlO 3 , achieved through the introduction of alkaline earth metal or transition metal cations holds the potential to notably enhance infrared radiation ability. However, it should be noted that the inherent emissivity of LaAlO 3 remains exceedingly low in the wavelength band of 2–14 µm 21,22 . It has been interestingly found that doping rare‐earth oxides (from Ce to Tm) with abundant electronic energy level structure can significantly improve the emissivity of thermal protective coating 14,18,23 …”
