Abstract
Experimental determinations of the absorptivity and of the total hemispheri cal emissivity of plasma-spayed ZrO2-7wt%Y2O3 layers were performed in the range of temperature 1000 K-2300 K. For this purpose, solar facilities of C NRS-IMP laboratory were used. The experimental set-up is described at 0.65 mum ranges from 0.10 below 1000 K to 0.75 at 2300 K, and the total hemisphe rical emissivity increases from 0.25 at 1300 K up to 0.60 at 2200 K.
