| Abstract: | Heating mixtures of lithium and nickel oxides at 1073°K under reduced oxygen pressure (<10?6 Torr) produces the incorporation of lithium ions in the nickel-oxide lattice. The solubility appears to be limited at 1.9 at Li %. From a study of several properties of solid solutions, it is concluded that the incorporation of lithium ions creates and stabilizes anionic vacancies. |
