Abstract
The description refers to a process for the production of a highly dispersed powder mixture in the process of comminution by grinding at least an element powder and an alloy powder in an oxygen-free atmosphere. The powder mixtures will serve in particular as the starting material to produce components and layers made of difficult to melt and sinter materials having intemetallic phases with closed porosity. The process is characterized by the fact that the comminution/grinding process is interrupted before formation of the intermetallic phase.
