Title: Magnetic powder and method of manufacturing the same
Inventor: SHIMOKAWA YOSHIHARU
IPC: H01F1/11
Filed: 1981-10-06
Abstract: PURPOSE:To attain magnetic powder with high coercive force and high intensity of saturated magnetization by adding rare-metal elements together with Co to Fe. CONSTITUTION:Magnetic powder contains Co, R.E. with Fe being a main ingredient. Co/Fe is 0.1-7wt% in atomic ratio, rare-metal elements/Co is 7-50wt% and iron consists of a needle crystal iron oxide, maghematitie (gammaFe2O3) or pure iron. Ce, Y, La, Sm, Pr, Cd, Tb, Dy, Ho, etc. can be used as rare-metal elements singularly or in the form of a mixture containing two or more among them. When both rare-metal elements and Co are used combinedly relative to iron oxide powder, the coercive force is improved up to a level of 700-800 oersted and the intensity of saturated magnetization sigmas becomes 80-90emu/g. Using of metal iron powder increases the coercive force up to a level of 1,100-1,300 oersted and results in metal powder with superior square ratio (sigmar/sigmas) and dispersibility.
