摘要：

A special apparatus for in situ X-ray diffraction measurements has been designed to investigate unstable intermediates that are formed during the anodic oxidation of nickel in molten Li2CO3-K2CO3, and can exist only under certain conditions. In preliminary experiments, the anodic oxidation of copper, which is well understood, has been used to test the apparatus. The result demonstrated that the in situ X-ray diffraction apparatus functions effectively. Using this apparatus, the mechanism of anodic oxidation of nickel in molten Li2CO3-K2CO3 has been investigated, and the higher nickel oxide earlier inferred from transient electrochemical measurements has been confirmed as Ni2O3. © 1990, Elsevier Sequoia S.A..
