Figure 14
MD snapshot of the atomic configurations calculated for the (LiF:ThF4) = (0.5:0.5) composition at T = 920°C. Orange: Li+ ions; green: Th4+ ions; grey: F− ions. Li+–Th4+ pairs at a distance less than the minimum of the radial distribution function (3.2 Å) are shown as bonds and considered to belong to the coordination sphere of the thorium. Red: seven-coordinated Th4+; blue: edge-sharing polyhedra; orange: face-sharing polyhedra; brown: 7 Th-long chain. |
