摘要
Topotactic proton exchange (Li against H) can be achieved by treating LiBnO3 with appropriate acids. In order to investigate the effect of proton exchange on Fe-impurities we studied LiNbO3:Fe powder material treated in sulphuric acid and LiNbO3:Fe single crystals treated in benzoic acid by Mössbauer spectroscopy. During the topotactic ion exchange only the Li-ions are exchanged for protons, whereas the Fe-impurities are retained in the material. © 1990 J.C. Baltzer AG, Scientific Publishing Company.
