Review: Thermal ceramic coatings as energy saving alternatives for high temperature processes

Reductions in energy consumption for high temperature processes are an important research topic, especially due to the ongoing energy crisis scenario. Based on the several possibilities of saving it, thermal coatings are an economical and technical viable possibility of tailoring the optical properties of a material surface. Although many studies have been published on the benefits of high emissivity and high reflectivity ceramic coatings, there is still a lack of a clear understanding on the correlation between thermal radiation heat transfer, solid state physics, and material science technology. This study aims to create a connection between these areas in order to provide basic guidelines for the correct use of thermal ceramic coatings, leading to achieving the maximum decrease in energy consumption by their use.
