Abstract

Gas chromatography is performed during the decomposition of barium titanyl-oxalate and the subsequent synthesis of barium titanate under nonisothermal conditions. It is shown that the path of the decomposition process is different under different heating conditions. A new mechanism of barium titanyl-oxalate decomposition and subsequent barium titanate synthesis under high heating rates is suggested. The change in mechanism is caused by barium titanyl-oxalate oxidation by free oxygen.
