Vaporization behavior of BaPuO3 was investigated by high-temperature mass spectrometry with a Pt Knudsen cell in the temperature range from 1,673 to 1,873 K. The vapor species of Ba(g) and BaO(g) were identified over BaPuO3 with the second phase of PuO2. It was suggested from the experimental results that the decomposition of BaPuO3 was expressed as the following equation;BaPuO3(s)=PuO2(s)+BaO(g)2BaO(g)=2Ba(g)+O2(g).The second- and third-law standard molar enthalpies of formation of BaPuO3 were evaluated to be -1,661 and -1,673 kJ mol-1, respectively, which almost agreed with the calculated values previously reported.
