The thermal decomposition of whole and ground crystals of Ba(MnO/sub 4/)/ sub 2/ was investigated in the temperature range 140 to l90 deg C. Activation energies for the acceleratory and decay coefficients were measured. Reaction during the main acceleratory period was presumed to proceed by the mechanism propesed for the decomposition of KMnO/sub 4/. The decay period followed the unimolecular law. Preirradiation in a gamma -ray source accelerated the thermal decomposition and the results are interpreted by a mechanism similar to that suggested for preirradiated KMnO/sub 4/. (auth)
