Abstract
When a mixture of beryllium power and finely dispersed uranium, prepared by the decomposition of its hydride, was heated, a substance was obtained which consisted in the main of UBe13 and a small quantity of free beryllium. From the difference between the heat of solution of UBe13 and of the corresponding mixture of its components, the heat of formation (−ΔH 0298 )UBe13 was determined. After corrections for impurities were allowed for, the heat of formation was found to be 39.3 ± 3.8 kcal/mole.
