[en] The new compounds A_2ZnP_2Se_6 (A = K, Rb, Cs) were synthesized via molten salt flux syntheses. The crystals feature one-dimensional "1/_∞[ZnP_2Se_6]"2"- chains charge balanced by alkali metal ions between the chains. K_2ZnP_2Se_6 crystallizes in the monoclinic space group P2_1/c; cell parameters a = 12.537(3) Aa, b = 7.2742(14) Aa, c = 14.164(3) Aa, β = 109.63(3) , Z = 4, and V = 1216.7(4) Aa"3. Rb_2ZnP_2Se_6 and Cs_2ZnP_2Se_6 are isotypic, crystallizing in the triclinic space group P anti 1. Rb_2ZnP_2Se_6 has cell parameters of a = 7.4944(15) Aa, b = 7.6013(15) Aa, c = 12.729(3) Aa, α = 96.57(3) , β = 105.52(3) , γ = 110.54(3) , Z = 2, and V = 636.6(2) Aa"3. Cs_2ZnP_2Se_6 has cell parameters of a = 7.6543(6) Aa, b = 7.7006(6) Aa, c = 12.7373(11) Aa, α = 97.007(7) , β = 104.335(7) , γ = 109.241(6) , Z = 2, and V = 669.54(10) Aa"3.

[en] The Concept of Choice of Lithium Containing Materials for Fusion Reactor Blanket is based on the following criteria: 1. the full coverage of the nuclear-physical, thermophysical, chemical, mechanical and other properties of materials; 2. the reliability of suggested blanket module designs loaded with lithium elements including conditions of tritium removal as well as heat removal; 3. feasibility of a tonnage production of the required materials that meet the first and second criteria.

[en] Using the spectral method the isotope analysis of lithium is carried out to specify the value of anomalies of lithium isotope composition in salts. Accuracy of the results obtained has been checked according to standard mixtures, prepared of isotopically enriched lithium chlorides (lithium-6 chloride-90.5% ⁶Li and 9.5% ⁷Li; lithium-7 chloride-0.02% ⁶Li and 99.98% ⁷Li). The analysis has shown that commercial salts of lithium can have considerably shifted isotope composition, which must be taken into account when calibrating the instruments and applying salts as standards of isotope ratio
