Hydrides and deuterides of lithium and sodium: model potentials and their use in defect lattice

Hydrides and deuterides of lithium and sodium: model potentials and their use in defect lattice. Haque, E.; Islam, A. K. M. A. (Dep. Phys., Rajshahi Univ., Rajshahi 6205, Bangladesh). J. Phys. Chem. Solids, 53(3), 377-82 (English) 1992. CODEN: JPCSAW. ISSN: 0022-3697. DOCUMENT TYPE: Journal CA Section: 76 (Electric Phenomena) Section cross-reference(s): 75 The reliability of a recently derived potential model is tested by studying the various defect properties, such as the intrinsic defect energies (Schottky, Frenkel and antisite-pair defect energies), activation and Arrhenius energies of migration for hydrides and deuterides of lithium and sodium. The predicted anion vacancy activation energies are smaller and comparable with the cation values. 15780-28-6 and 7580-67-8 which are cas registry numbers of chemicals are mentioned. The values thus obtained are insufficient to explain the curvature in the cond. plot of ionic (lithium) compds. Both interstitials and vacancies play an important role in the ionic conduction of hydrides and deuterides of lithium and sodium. Finally, a comparison of the calcd. properties with the exptl. data (where available) shows the validity and reliability of the derived potentials. .
