Structures and Properties of Rare-Earth Molten Salts

摘要: Abstract There is a definite overlap between the concepts of molten salts and ionic liquids; however, present tendency to use “molten salts” characterize melts purely inorganic compounds. If theoretical modeling crystals relatively easy achieve from X-ray diffraction data in view periodic arrangements ions structure, it becomes much more involved process when are considered because interparticle interactions due collisions. A single experimental technique usually gives partial picture situation only so that multiple-technique approach has be used combining for instance diffraction, vibrational spectroscopy, density measurements, molecular dynamics, Monte Carlo calculations. The review first focuses on definition radial distribution function ways estimate coordination numbers second shell this function. It then describes knowledge rare-earth alkali halides further concentrates with polyatomic anions. penetration into sphere discussed as well formation polymeric their clustering. Kinetic aspects also given attention.
