Novel coating method for manufacturing solar absorbers
A new coating process has been developed at the Institute of Powder Technology of Glass and Ceramics of Saarland University. The technology enables a relatively simple and costefficient manufacturing of solar absorbers. A suspen-sion of ceramic and metal powder particles is applied to the solar absorbers and then dried. By means of the new tech-nology it is possible to produce a vast variety of coatings (e.g. SiO2, Al2O3 as ceramic and Fe, Cu or Ni as metal com-ponent).
