The authors prepared foils 60-70 micron thick from Pt-Cm alloys containing up to 3 at. % of curium-244. The foils were studied by x-ray diffraction, chemical analysis, and metallography. The alloys consisted of two phases, pure platinum and the intermetallic compound Pt5Cm. The curium was only slightly soluble in platinum at room temperature. The curium distribution in the bulk foil deviated by no more than 10% of the average. Curium leachability by water under standard conditions decreased from 0.1-0.5% for freshly prepared foils to 0.010.02% for a second leaching and then to 0.005-0.006% after supplementary baking in hydrogen. Marked selective dissolution of curium from the foils took place in nitric acid and increased with a rise in acid concentration.
