Abstract

Barium aluminates have been obtained by the method of continuous precipitation at different values of pH. The method of thermal analysis showed that the main mass losses which are connected with dehydration processes occur in the temperature interval from 50°C to 100°C and from 150°C to 200°C. In addition, mass loss occurs in the temperature interval from 780°C to 1000°C which can indicate barium aluminate formation. XRD analysis was applied to determine phase composition of obtained substance and showed formation of Ba1.17Al10.67O17.17 and BaAl2O4 at pH 6.5; 7.0 and 7.5 respectively. Significant influence of pH on precipitation composition has not been detected.
