Abstract

Disclosed are a method for producing a cobalt carbonate of low alkali metal content at a low cost in high productivity, and a cobalt oxide of low alkali metal content and high performance produced from the cobalt carbonate. The method comprises reacting an aqueous cobalt salt solution with a carbonate of an alkali metal to produce the cobalt carbonate; wherein: (1) a reaction temperature is controlled at less than or equal to 25°C, and/or (2) an aqueous solution of the carbonate of an alkali metal containing a hydroxide of the alkali metal in an amount of 5 to 40g/L is used as the carbonate of the alkali metal.

Claims (7)

1. A method for producing cobalt carbonate of low alkali metal content, which comprises:
reacting an aqueous cobalt salt solution with a carbonate of an alkali metal to produce the cobalt carbonate, under at least one of the following conditions:
(1) a reaction temperature is controlled at 25°C
or lower, and (2) an aqueous solution of an alkali metal carbonate containing an alkali metal hydroxide in an amount of 5 to 40g/L is used as the carbonate of an alkali metal.
2. The method according to claim 2, wherein the carbonate of an alkali metal is a sodium salt.
3. The method according to claim 2, wherein the carbonate of an alkali metal is sodium bicarbonate.
4. The method according to claim 1, 2 or 3, wherein the reaction temperature is controlled at 10 to 20°C.
5. The method according to claim 1, 2, 3 ar 4, wherein the alkali metal hydroxide is sodium hydroxide.
6. Cobalt carbonate of low alkali. metal content produced by the method according to any one of claims 1 to 5.
7. Cobalt oxide of low alkali metal content produced from the cobalt carbonate according to claim 6.
