| titleOfInvention | Fine iron powder containing phosphorus |
| abstract | A process for producing finely divided phosphorus-containing iron involves gaseous phase reaction of iron pentacarbonyl with a phosphorus compound, preferably phosphine. Preferably, the reaction is carried out in the presence of ammonia at above 200 degrees C. Also claimed is a finely divided phosphorus-containing iron which consists of spherical particles with 1-10 mu mean particle diameter or of filament aggregates of spheres with 0.2-3 mu diameter. Preferably, the iron contains 0.1-50 wt.% P, less than 1 wt.% C, less than 1 wt.% N, less than 0.5 wt.% H and less than 0.1 wt.% total of other impurity elements and is produced by the above process. Further claimed is apparatus for carrying out the above process, including a heated decomposition tube, devices for producing two different temperature zones, for evaporating liquid iron pentacarbonyl and for gas dosing and mixing, and a separator for finely divided phosphorus-containing iron. |
