Abstract
The vaporization behavior of SrPuO3 was investigated by mass-spectrome try with the Pt Knudsen-cell in the temperature range 1433-1913 K. The vapor species of Sr(g) and PuO(g) were identified and SrPuO3 was sugg ested to decompose into Sr(g), PuO2(s) and O-2(g). The standard molar enthalpy of formation of SrPuO3 was determined from the Vapor pressure s of Sr(g) and PuO(g) by using the free energy function and heat conte nt of SrPuO3(s) estimated by the authors. Furthermore, the measurement was also carried out in the graphite Knudsen-cell in order to investi gate the effect of oxygen potential on the vaporization behavior of Sr PuO3.
