Study of Optical Parameters of Semitransparent Materials for Heat-Insulating Coatings of Combustion Chamber

A new approach to evaluate optical parameters of new semitransparent materials which can be used for heat-insulating coatings of combustion chamber (chamber ([[illegible]]) is discussed. Theoretical predictions and experimental estimations of the parameters are analyzed with particular attention to those of model samples based on granulated powder of the stabilized zirconium oxide (ZrO₂ + 10% Y₂O₃). A setup is described designed to measure the reflection and transmission coefficients of the flat samples semitransparent materials. Possible applications of the semitransparent ceramic heat-insulating coatings in CC are outlined.
