HARD MAGNETIC COMPOSITIONS FROM IRON OXIDE FINES AND METHODS FOR MAKING SAME |
| 摘要 |
Disclosed herein are compositions and methods of making a hard magnetic material from iron oxide fines, the hard magnetic material having a general formula MFexOy. In one aspect, the method comprises a) providing an iron oxide fine; b) providing a metal carbonate of a general formula Mx(CO3)y; c) mixing the iron oxide fine and the metal carbonate to form a mixture; d) calcining the mixture of the iron oxide fine and the metal carbonate; wherein M is a divalent metal ion. |
