    摘要: The invention relates to a method for preparing silicon-containing iron powders by thermal decomposition of a gas mixture comprising iron pentacarbonyl and, as a volatile silicon compound, a silane or a halogen-free organosilane in which the gas mixture flows through a heated reaction chamber and heating of the gas mixture is effected by thermal conduction. The silicon-containing iron powders obtained are distinguished by a particularly low impurity element content. The silicon-containing iron powders can be used for the fabrication of cores, magnets and radar-absorbing materials.
