Non-stoichiometric titanate Cs - D2x - D2Ti - D22-x/4 - D2O - D24 - D2是a层结构compound withthe lepidocrocite （FeO(OH)）相关结构Cs d20 .68 D2Ti d21 .83 D2O D24 D2(x=0.68 in Cs D2x D2Ti D22-x/4 D2O D24 D2) isquantitatively ion exchanged with hydrated H - D1+ hydratedLi - D1+ Li - D1 and Na - D1+ Li - D1 using aqueous solutions. The ionic conductivities of The products arecomparable to those of the layered clay minerals of vermiculite and montmorillonite in which mobilecations are hydrated. Interlayer Cs ions are also ion exchanged with transition metal ionsof Ni D12+ D1，D12+ D1 and Co - D12+ D1 through Li - D1+ D1 exchanged product. These products werecharacterized by UV-VIS-NIR measurement。
