چکیده انگلیسی
This paper presents some experimental results for the recombination coefficient γ and the thermal flux of recombination transferred to the material in the surface-catalyzed recombination of oxygen atoms based on experiments performed on the MESOX set-up using optical emission spectroscopy, actinometry and calorimetry techniques. Experimental results on the recombination coefficient are presented for three types of α-Al2O3 in the temperature range 900-2400 K for 300 Pa total air pressure. The thermal flux of recombination is given for only two representative samples. These three alumina differ essentially by their content of sintering additives. Different behaviors of the recombination coefficient versus temperature are observed according to the impurity level of the α-alumina.
