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.
Description
Technical field
The present invention relates to a kind of method preparing nickelous carbonate.
Background technology
NiCO
3be the crystallization of oblique side's light green, namely more than 300 DEG C decomposed.Can be dissolved in ammoniacal liquor and diluted acid, water insoluble.Generally reacted by alkaline carbonate and single nickel salt and obtain, be usually used in the painted and glaze of plating, battery, ceramic ware etc.Nickelous carbonate is that one prepares the effective a kind of presoma of synthesis of nano nickel, high by the nano nickel purity prepared by it, and reaction conditions is gentle.
About preparing the method for nickelous carbonate, main to obtain with alkaline carbonate and single nickel salt chemical reaction, to environment and processing requirement high, the waste liquid of alkali metal containing ion can be produced, difficult harmless treatment.Therefore be necessary that exploitation preparation technology is simple, efficiency is high, without the need to the preparation method of specific installation facility, to overcoming the shortcoming of aforesaid method.
Summary of the invention
The object of this invention is to provide a kind of compared with the method preparing nickelous carbonate under mild conditions.
Nickelous carbonate preparation method of the present invention, comprises the following steps:
1) be fully dissolved in the water by nickel ammonium sulfate, the nickel ion concentration of preparation is the aqueous solution of 0.1 ~ 1mol/L;
2) joined by bicarbonate of ammonia in the nickel salt solution that step 1) configures, the mol ratio of bicarbonate of ammonia and nickel salt is 4:1 ~ 6:1, at room temperature stirring and dissolving evenly after, load autoclave, closed reactor, is heated 210 ~ 250 DEG C, insulation 2-8 hour;
3) by step 2) product of gained filters, repeatedly cleans with water, dry, after 260-295 DEG C of heating, can obtain nickelous carbonate powder.
Above-mentioned steps 2) in the mol ratio of preferably bicarbonate of ammonia and nickel salt be 5:1.
The present invention has the following advantages:
1) obtained product purity is high, and productive rate is high.
2) technique is simple, and production cost is low, with short production cycle, mild condition.
