An investigation was undertaken to obtain information concerning the influence of various factors on the rate of dissolution of massive uranium metal in HNO₃. The initial rate increased with increasing carbon and nitrogen content. The amount of ""work'" the sample received increased the rate, particularly if the carbon content was high. Samples of metal which were worked also dissolved more rapidly along the axis of the rod from which they had been cut. The rate of the reaction increased as the reaction proceeded because of the accumulation of HNO₂ and an increase in surface area. With increasing concentration of HNO₃, the rate increased to a maximum at 13 to 14N and then it decreased. The metal became passive in dilute acid.
