Abstract (en)

[origin: WO0157279A1] The invention relates to agglomerates containing iron and at least one other element from groups 5 or 6 of the periodic table, in particular, molybdenum or tungsten. The invention is characterised in that said agglomerates have a porosity in the range from 20 to 65 vol %, in particular, from 30 to 45 vol %. A rapid dissolution in a metal melt is thus achieved. According to the invention, the agglomerates, in particular, contain molybdenum as the further element, preferably in an amount in the range of 60 to 80 wt. %. The particle density of said agglomerates is preferably 4.2 to 6.3 g/cm3. Said agglomerates are produced by reduction of a mixture of iron oxide and molybdenum, whereby the reduced metal is formed into briquettes without the addition of any binders and the Fe-Mo product in briquette form is then sintered.
