Description

Dauermagnetwerkstoff auf Oxydbasis Zusatz zur Patentanmeldung L 13006IVc/80b Gegenstand der Patentanmeldung L 13006 IVc / 80b ist ein magnetischer Werkstoff, der aus einem Gemisch von Metalloxyden besteht und sich besonders als Dauermagnetwerkstoff eignet. Er enthält Eisenoxyd (Fe203), Bleioxyd (Pb0) und Siliziumoxyd (Si02). In einer Mischung von 65 bis 85 Molprozent Fe, 0, 35 bis 15 Molprozent Pb0 und 0,5 bis 8 Molprozent Si02 ergeben die gemessenen Werte eine Remanenz von Br = 1400 Gauss und eineMagnetisierungskoerzitivkraft von iHC = 3900 0e. Eine Verbesserung der Remanenz dieses Dauermagnetwerkstoffes wird erfindungsgemäß dadurch erreicht, daß der Anteil an Bleioxyd bis 75 °/o, insbesondere etwa 50°/o seines Anteils durch Bariumoxyd (Ba0) und/oder Strontiumoxyd (Sr0) ersetzt ist.Permanent magnet material based on oxide Addition to patent application L 13006IVc / 80b The subject of patent application L 13006 IVc / 80b is a magnetic material that consists of a mixture of metal oxides and is particularly suitable as a permanent magnet material. It contains iron oxide (Fe203), lead oxide (Pb0) and silicon oxide (Si02). In a mixture of 65 to 85 mole percent of Fe, 0, 35 to 15 mole percent of Pb0 and 0.5 to 8 mole percent of Si02, the measured values are obtained by a remanence Br = 1400 gauss and eineMagnetisierungskoerzitivkraft of iHc = 3900 0e. An improvement in the remanence of this permanent magnet material is achieved according to the invention in that the proportion of lead oxide up to 75%, in particular about 50%, of its proportion is replaced by barium oxide (Ba0) and / or strontium oxide (Sr0).
