根据Hume Rothery规则 ,分析了银与镧两元素之间形成金属间化合物的倾向性 ,并根据真空蒸发沉积的条件 ,分析了在真空蒸发沉积情况下镧与银之间形成金属间化合物的可能性 .用X射线光电子能谱化学位移方法对真空蒸发沉积的银、镧薄膜进行了分析 ,结果表明在真空沉积条件下镧与银之间的确形成了金属间化合物 .
According to the Hume Rothery rule, the tendency of formation of intermetallic compounds between silver and lanthanum was analyzed, and the possibility of forming intermetallic compounds between lanthanum and silver under vacuum evaporation deposition was analyzed according to the conditions of vacuum evaporation deposition The X - ray photoelectron spectroscopy chemical shift method was used to analyze the silver and lanthanum films deposited by vacuum evaporation. The results show that the intermetallic compounds did form between lanthanum and silver under vacuum deposition conditions.
