THE FORMATION AND GROWTH OF NANOSTRUCTURAL CRYSTALS OF CERATH BARIA UNDER THE INFLUENCE OF THE FLOW OF HIGH-ENERGY ELECTRONS
In the article presents the results of the formation of the nano- and microstructure of BaCeO3 cerath baria, irradiated by electrons with 1.3 MeV energy with variation scan doses of radiation 1,5,7,10 and 14 MGy. The studies were carried out by x-ray analysis (RFA), rastra electron microscopy (REM), atomic-force microscopy (ASM), differential thermal analysis (DTA). DTA BaCeO3 has shown that there is an endothermic peak of 950oC, which can be caused by the phase transition of the ortocombical lattice into a cubic grid with the Рm3m structure. Increasing doses of electron exposure to cerath baria has an effect on the increase in its temperature, leading to a consistent transformation of the structure of cerath baria through phase transitions. It is shown that in the process of electronic irradiation of high energies 1.3 MeV and large doses of radiation in the microstructure of the cerath barium BaCeO3 formed colonies of nanocrystals in parallel oriented relative to each other with sizes in diameter of 5 to 10nm and long of 20 to 170 nm.
