Abstract
The sintering of uranium powder has been studied under different conditions with the main objective of making shaped charge liners by powder metallurgy. It is shown that pressureless sintering of uranium powder yields a density below 11.4 Mg/cu m, 60% of the theoretical density, that the density obtained by isostatic cold pressing varies between 12 and 16 Mg/cu m for pressure between 276 and 1656 MPa, and that a density of 17.5 Mg/cu m can be obtained by hot pressing. Hot pressing experiments at different pressures and temperatures also show the influence of the particle size on the shrinkage of uranium powder and a sudden increase in shrinkage at 983oK. All the experiments were performed either with a commercial uranium powder or with a very fine powder obtained by decomposition of uranium hydride.
