Abstract
The result of structural investigation of BaO2 powder samples exposed to intensive mechanical treatment in the disintegrator are presented. X-ray patterns of the powders under study displayed features involving significant broadening and changes in positions of X-ray peaks at the certain stage of treatment. The structural instability which manifested in discontinuous jump of lattice parameters, is observed. Assumptions of the reasons causing a sharp leap of lattice parameters and broadening of X-ray lines have been made. Correlation between structural instability and solubility of BaO2 has been established.
