S 53 Shein, I. R. Elastic properties and chemical bonding in fluoritelike Be2B, AlBeB, MgBeB, and NaBeB [Текст] / I. R. Shein, A. L. Ivanovskii // Journal of Structural Chemistry. - 2005. - Vol. 46, № 3. - С. 535-537. - Библиогр. : с. 537 (7 назв.) Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): ФЛЮОРИТОПОДОБНЫЕ БОРИДЫ -- УПРУГОСТЬ -- ХИМИЧЕСКИЕ СВЯЗИ Аннотация: Calculations of lattice constants and elastic moduli were carried out by means of FP LMTO-GGA for fluoritelike beryllium semiboride Be2B and its ternary phases on its basis: AlBeB, MgBeB, and NaBeB. Changes in the indicated parameters are discussed from the viewpoint of chemical bond rearrangement in ternary boride phases. Полный текст |
