Contribution à l’étude thermodynamique du système Pb-Bi-(Hg)-Fe-(Al,Cr)-O : étude des systèmes Bi2O3–PbO–Al2O3 et Bi2O3–PbO–Fe2O3

Abstract : This research work takes part in a global project whose aim is to understand and solve a corrosion problem of a steel called T91 caused by a liquid mixture of lead-bismuth. It presents a great interest for the nuclear community who aims to develop a new generation of reactors called ADS. This study is a contribution to the thermodynamic study of a complex system involving several elements such as Al, Bi, Pb, Fe, Cr and oxygen. More precisely, it was focused on mixtures of the following oxides Bi2O3 + PbO + Al2O3 and Bi2O3 + PbO + Fe2O3. A long experimental work had been accomplished, in which mixtures of different proportions of these oxides were prepared and heated above 600 °C for several days, followed by samples analyses by use of accurate and advanced techniques. It allowed discovering the different products formed within the different experimental conditions. The results have been modeled using a computer tool. All this allowed a better understanding and anticipating the corrosion products formation of the T91 steel by the metallic liquid
