Patent ID: 8052806

Claim:
An iron powder consisting of electrically insulated, iron base powder particles, which have a particle size less than 100 μm, wherein the iron base powder has an oxygen content less than 0.1% by weight, the electrically insulated, iron base powder particles has a total oxygen content, O tot , at most 0.8% and a total phosphorus content at least 0.04% by weight higher than those of the iron base powder particles such that the quotient of the total oxygen content of the electrically insulated, iron base powder particles and the difference between the total phosphorus content of the electrically insulated, iron base powder particles and the iron base powder particles, ΔP, is between 2 and 6 and where the relation between the total oxygen content of the electrically insulated, iron base powder particles, and the difference between the total phosphorous content of the electrically insulated, iron base powder particles and the phosphorous content of the iron base powder particles, ΔP, and mean particle size, D 50 , expressed as ΔP/(O tot *D 50 ) is between 4.5 and 50 1/mm.
