Californium oxygen system for 1.50 < O/Cf < 1.72

PDF Version Also Available for Download.

Description

The californium-oxygen system was studied as a function of temperature, oxygen pressure, and stoichiometry by manometric and x-ray diffraction methods. The results establish rhombohedral Cf$sub 7$O$sub 12$ as the stable compound obtained by heating Cf$sub 2$O$sub 3$ in air. The isobaric oxidation-reduction cycles Cf$sub 2$O$sub 3$ $Yields$ Cf$sub 7$O$sub 12$ $Yields$ Cf$sub 2$O$sub 3$, observed in constant rate of heating (cooling) experiments, occur with large hysteresis. A close parallel to other fluorite related lanthanide and actinide oxide systems is established. (auth)
