POROUS AGGLOMERATES CONTAINING IRON AND AT LEAST ONE FURTHER ELEMENT FROM GROUPS 5 OR 6 OF THE PERIODIC TABLE FOR USE AS AN ALLOYING AGENT, PROCESS FOR PREPARING THE SAME, AND ALLOYING AGENT COMPRISING THE SAME

摘要

The invention relates to agglomerates containing iron and at least one further element of groups 5 or 6 of the periodic system, characterized in that they have a porosity in the range of 20 to 65% by volume, in particular of 30 to 45% by volume. Hereby, a rapid dissolubility of the agglomerates in a metal melt is achieved.
