摘要： The invention relates to Fe Nd B type alloys for permanent magnets, the permanent magnets thus obtained and a method of producing them.They have high magnetic characteristics with good temperature resistance and good resistance to atmospheric corrosion.They comprise, in at%, 12 to 18% of rare earths, 3 to 30% of Co, 5.9 to 12% of B, 2 to 10% of V, some Al and Cu, the remainder being iron and unavoidable impurities. The V can be substituted by other refractory elements (Nb, W, Cr, Mo, Ti, Zr, Hf, Ta).The method mainly involves sintering at between 1050 and 1110.degree. C. followed by annealing at between 850 and 1050.degree. C. and/or artificial ageing at between 560.degree. C. and 850.degree. C.

摘要： A method for manufacturing type M hexaferrite powders fo the formula AFe12O19 where A is Ba, Sr, Ca, Pb or a mixture thereof. An iron oxide Fe2O3 and a compound A are mixed with a molar ratio n=Fe2O3/AO, formed and calcined, and the agglomerates which result from the calcining are ground to obtain a fine ferrite powder. The mixture is formed with a ratio n ranging between 5.7 and 6.1, and with a predetermined degree of homogeneity, and before or during the grinding process, an agent controlling the microstructure is introduced.
