Research of the possibility of synthesis the complex oxide with by structure of perovskite in the system La-Ce-Pr-Nd-Sm-Mn-O

摘要

The possibility of formation of the complex oxide with by structure of perovskite in the system La-Ce-Pr-Nd-Sm-Mn-O was studied the methods of X-Ray-structure and X-Ray-phase analysis, thermogravimetry and IR-spectroscopy. Is established, that as a result of interaction in system two cubic phases will be formed: the phase on the base of CeO_2 with constant lattice a=5.4(9) A and complex oxide with by structure of perovskite of the type of loparite and parameter a=5.40(7) A.
