摘要
用共沉淀还原扩散法成功地制备了新的镧系吸氢合金LaNi4Cu1-xMnx(x=0.25,0.5,0.75),对合金进行了XRD、SEM、吸氢测试和热力学研究,结果表明,这些合金易活化,吸氢容量较高,其氢化物的稳定性与合金的晶胞体积之间存在线性关系。
Three new quarternary hydrogen_absorbing alloys of the type LaNi 4Cu 1-x Mn x(0<x<1)were prepared using Coprecipitation_Reduction_Diffusion Method. Their structure and properties were studied by means of XRD, SEM and hydrogen_absorbing measurement. These alloys can be easily activated, and have high hydrogen capacity. A linear correlation was found between the hydride stability and the crystal cell volume of these alloys, which is useful in predicting the stability of hydrides.
