本文报道采用不同工艺获得亚稳态氧化物LaFe_yNi_(5-y)H_6,并在室温下对LaFe_yNi_4Hx进行了X射线衍射测量和Mossbauer效应的研究,得到一些有关氢化物相变的信息。
The metastable hydrides LaFe_yNi_(5-y)H_x of higher hydrogen concentration were prepared by the activation treatment technique under 353—373K and 60—120 kgf/cm~2 hydrogen pressure other than the previous ones. The X-ray diffraction and Mossbauer effect of the LaFe_yNi_(5-y)H_x (0≤x≤1.6) were examined at room temperature. Some interesting informations about their phase transition were given.
