Выдержка

Thermal deformations of Na6(UO2)2O(MoO4)4 were studied by high-temperature powder X-ray diffraction. The compound crystallizes in the triclinic system, space group P $$\bar 1$$, a = 7.636(7), b = 8.163(6), c = 8.746(4) Å, α = 72.32(9)°, β = 79.36(4)°, γ = 65.79(5)°, V = 472.74(4) Å3. It is stable in the temperature interval 20-700°C. The thermal expansion coefficients (TECs) are α11 = 25.5 × 10-6, α22 = 7.8 × 10-6, and α33 = 1.1 × 10-6 (°C)-1. The orientation of the TEC pattern relative to the crystallographic axes is a 33^Z = 45°, a 33^X = 122°, a 22^Z = 59°, and a 22^X = 66°. The anisotropy of the thermal expansion is due to specific features of the crystal structure of the compound.
