Заглавие : Nanostructured composite materials of cerium oxide and barium cerate Место публикации : Russian Journal of Physical Chemistry A. - 2013. - Vol. 87, № 2. - С. 270-277 ББК : 54 Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ Ключевые слова (''Своб.индексиров.''): церат бария--оксид церия--композиционные материалы--наноразмерные порошки Аннотация: Nanosized powders with a composition of (1-x)Ce0.8Sm0.2O2-δ-xBace0.8Sm0.2O3-δ (x = 0, 0.3, and 1) were obtained by self-ignition combustion synthesis (SICS) from the appropriate nitrates and various organic fuels (glycine, glycerol, citric acid, and a mixture of citric acid and ethylene glycol). The most finely dispersed powders formed when the concentration of the perovskite phase in the system decreased or when glycerol or citric acid-enthyleneglycol mixture was used as a fuel during SICS. A procedure for the preparation of powders and nanostructured ceramics was developed and their electric properties were studied. Доп.точки доступа: Medvedev, D. A.; Pikalova , E. Yu.; Demin , A.
