【摘要】 根据对CO和H₂与Pu,PuO,Pu₂O₃,PuO₂反应自由能变的计算,提出CO-H₂系统能使钚表面趋于比较致密和稳定的Pu₂O₃晶体表面形成“钝化膜”,以阻止CO和H₂气体进一步向内扩散而保护金属钚。更多还原

【Abstract】 The calculated results of the temperature dependence of standard Gibbs free energy change AG of the reactions of CO and H2 with Pu, PuO, Pu2O3, PuO2, respectively, show that the CO-H2 system enables a passive surface film to be formed on the compact and stable crystal surface of Pu2O3 to prevent the metallic plutonium from further crossion by the inward diffusive CO and H2 gas. It is presumably like the protecting aluminum surface with its oxidized layer.更多还原
