| titleOfInvention | Preparation method of oxide or meta-coated nickel ultrafine powder |
| abstract | The invention relates to a preparation method of oxide or meta-coated nickel ultrafine powder. The preparation method is characterized by comprising the following steps of: (1) respectively adding water-soluble nickel salt and precipitator into deionized water, so that two solutions can be obtained; (2) respectively adding dispersing agent into the two solutions; (3) mixing the two solutions; (4) respectively adding another water-soluble metal salt and precipitator into deionized water, so that two solutions can be obtained; (5) simultaneously adding the obtained two solutions into single-precursor solution; (6) carrying out solid-liquid separation, and drying, so that a salt-coated precursor can be prepared; and (7) heating to 500-1200DEG C, keeping the temperature for 0.5-5h, cooling along with a boiler, and cooling to the room temperature, so that the coated power can be obtained. The ultrafine coated power prepared by the method is approximately spherical in appearance, has the average grain diameters of 200-500nm, and is high in crystallinity; and the prepared spherical power is free of glomeration, good in dispersity, and high in oxidation resistance. |
