A new process, termed pressureless sintering, has been established for the production of beryllium shapes (solid or hollow) to near theoretical density. It consists simply of the vacuum sintering at 1,200 deg C of loose powder of critical particle size distribution, without the application of pressure. Notable advantages are claimed over conventional powder production and consolidation methods. The process is particularly suited for the production of beryllium fuel cans, structural components, and moderators for reactor application. Particular significance is attached to the direct production of beryllium canned fuel elements by sintering loose powder around a uranium ceramic core. (auth)
