Abstract: For the production of iron powders largely free from carbon, nitrogen and oxygen, the said powders are treated with hydrogen at elevated temperatures, with the addition of an organic substance. There is used as the iron powder one which has been obtained by the decomposition of an iron pentacarbonyl in the presence of an oil which volatilises with difficulty.

Abstract: Iron oxide pigments with covering properties are obtained by combustion of iron carbonyl. For this purpose, the iron pentacarbonyl is introduced into a layer of iron oxides which is moved mechanically and oxidised to iron oxides at temperatures of 100 to 400 DEG C.

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.

Abstract: A process for producing phosphorus-containing iron powder involves heating a mixture of finely divided carbonyl iron and elemental phosphorus and pulverising the product. Preferably, a mixture of 70-99 wt.% finely divided carbonyl iron powder and 1-30 wt.% red phosphorus is heated at above 300 degrees C in an inert gas atmosphere. Also claimed is a phosphorus-containing iron powder of less than 10 mu mean particle diameter, containing 0.1-80 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 except oxygen.
