Abstract

The invention concerns a process permitting the preparation of a new powder, which as such or further processed is useful within a wide variety of different fields and which has magnetic and electric properties. The powder includes at least 0.5% by weight of iron containing silicate and at least 10% by weight of metallic iron and/or alloyed iron and is prepared by a process comprising the steps of mixing an iron containing powder and a silicon containing powder; and reducing the obtained mixture at a temperature above about 450° C.
