Abstract
The invention relates to a nickel carbonate preparation method. The method includes the steps that ammonium nickel sulfate is fully dissolved in water, and a nickel salt aqueous solution is prepared; ammonium bicarbonate in a certain proportion is added into the nickel salt aqueous solution and stirred and dissolved at room temperature, the mixture is placed in a high-pressure reaction kettle with a polytetrafluoroethylene lining and heated to 210-250 DEG C in a closed mode, and the temperature is preserved for 2-8 hours; the obtained product is filtered, repeatedly washed with water and dried; after heating at the temperature of 260-295 DEG C, nickel carbonate can be obtained. The preparation method has the advantages of being simple in preparation technology, cheap in raw material, short in production period, mild in condition, high in production purity, uniform in appearance and the like.
