摘要： A process for preparing carbonyl iron silicide comprises heat treatment of an iron/silicon mixture comprising a) from 20 to 99.9% by weight of finely divided carbonyl iron and b) from 0.1 to 80% by weight of finely divided silicon powder. Also provided are a carbonyl iron silicide obtainable by alloying carbonyl iron with silicon and a carbonyl iron suicide which has a higher inductance than carbonyl iron powder.
