摘要: 由于E0Tb4+/Tb3+=+3.1V,使得Tb(Ⅳ)很难以简单离子的形式存在于水(E01/2O2+2H+=+1.22V)溶液中。要从水溶液中获得稳定的Tb(Ⅳ),必须降低其平衡电位,通常采用生成难溶盐、配合物或溶胶等方法。

Abstract: The compositions of the oxidation products of Tb (Ⅲ)by ozone in K2CO3-KOH solutionwere studied by elemental analyses, infrared spectra and X-ray powder diffractometry.The results indicated that the oxidation.products are hydrated oxides TbO2·xH2O ratherthan basic carbonate of Tb.

Key words: terbium, oxidation
