Porous agglomerates containing iron and at least one further element from groups5 or 6 of the periodic table for use as an alloying agent

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.
