A component or semifinished product is produced of a material of the group comprising molybdenum, molybdenum alloy, tungsten and tungsten alloy with an average relative density of >98.5% and a relative core density of >98.3%. The material is sintered to a relative density D, with 90%0.8 and also hot-isostatically pressed at a temperature 0.40 to 0.65.times.solidus temperature and under a pressure of from 50 to 300 MPa. Components produced in this way, used for example as electrodes, have much improved service life characteristics.
