Structure investigation of defect MgO - high temperature process catalyst

Structure refinement of defect MgO containing acetate and carbonate groups has been performed. The experiment was carried out on high resolution powder diffractometer in Siberian Synchrotron Radiation Center, Novosibirsk. The results demonstrated possibility of admixtures to insert into the structure of MgO by two different ways. The reliability of both models has been estimated. These models provided the decrease of R-factor down to 2.0-2.2% in contrast to the ideal MgO structure R-factor (9.5%).
