Polycrystalline sintered compacts based on europium hexaboride and process for their manufacture

The invention relates to polycrystalline sintered compact based on europium hexaboride having a density of at least 85% of the theoretical density. The compacts comprise EuB6, from about 0.1 to 10% by weight of B4C and, optionally, amorphous carbon, and have a total of Eu+B+C of at least 98.5% by we...
