| titleOfInvention | A kind of additive and method improving permanent-magnet ferrite magnetic property |
| abstract | A kind of additive and method improving permanent-magnet ferrite magnetic property, the additive are made of calcium carbonate, quartz sand and silicon carbide.The method includes the following steps：（1）Permanent ferrite prefiring material is added in ball mill, while the additive is added, then plus water, ball milling obtain permanent ferrite slurry；（2）Permanent ferrite slurry is precipitated and is filtered, permanent-magnet ferrite filtering slurry is obtained；（3）Permanent-magnet ferrite filtering slurry is injected into mold, under conditions of 450~950kA/m of magnetic field intensity, pressurize 350~500kg/cm 2 Molding, obtains permanent-magnet ferrite green compact；（4）Permanent-magnet ferrite green compact are sintered 0.5~3.0h at 1150~1250 DEG C, obtain permanent-magnet ferrite.Additive of the present invention is of low cost, raw material sources are extensive, does not add the expensive additives such as rare earth element and cobalt oxide；The magnetic property of the method for the present invention magnet compared with traditional method is more excellent, cost performance higher. |
