Azarska O. Interaction of Lithium with Тi, V and Sn, Pb, Sb and Bi.

The isothermal sections of the Li-{Тi, V}-{Sn, Pb, Sb, Bi} phase diagrams over the whole concentration range were constructed by X-ray diffraction and partially microstructure and EDX analyses at 200 С. The existence of 16 new ternary compounds was identified and the crystal structure was discovered for 14 of them. The new structure type Li1.25Ti2Sb was determined and described. The crystal structure of the ternary stanides of lithium Li11V2+хSn5-х and Li11-хTi2+х+ySn5-y (superstructure to Li13Sn5) was determined by X-ray powder diffraction. The half of 16 ternary compounds found in ternary systems crystallise in the Heusler-type phases or the related to them. The homogeneity ranges of 34 solid solutions of substitution, 4 solid solution of substitution-inclusion were investigated. The ternary compound LixTi5Sn4-x is a derivative of including from the Ti5Sn3 binary compound. The distribution of ternary compounds in the Li-T-X systems (T - transition element, X - р-element of IV and V group) was studied. The dependence of disordered CaF2 and BiF3 structure types and their ordered variants from the difference in size and electronegativity of elements as well as from the ratio of atomic radia was analysed.
