Magnetic ceramic material and preparation method thereof
The invention discloses a magnetic ceramic material and a preparation method thereof. The magnetic ceramic material is prepared from the following components in parts by weight: 55-62 parts of zirconium dioxide, 20-25 parts of magnesium oxide, 5-12 parts of epoxy soybean oil, 5-8 parts of calcium carbonate fibers, 2-3 parts of ferroferric oxide, 1.5-2.5 parts of antimony mercaptide, 0.5-2 parts of antimonous oxide, 0.5-1 part of cobalt sulfide and 0.05-1 part of copper. The invention further provides the preparation method for the magnetic ceramic material, wherein the method comprises the following steps: (1) weighing 55-62 parts of zirconium dioxide, 20-25 parts of magnesium oxide, 1.5-2.5 parts of antimony mercaptide, 0.5-2 parts of antimonous oxide, 0.5-1 part of cobalt sulfide and 0.05-1 part of copper, and stirring for 10-20 minutes at a high speed at 50-80 DEG C; (2) adding 2-3 parts of ferroferric oxide, 5-8 parts of calcium carbonate fibers and 5-12 parts of epoxy soybean oil which are sufficiently milled into a product obtained in the step (1), performing spray granulation, pressing for molding, and sintering for 2-3 hours at 1350-1380 DEG C to obtain the magnetic ceramic material.
