| titleOfInvention | METHOD FOR PRODUCING CALCIUM CARBONATE WITH SURFACE REJECTED SURFACE TREATMENT AND ITS APPLICATION |
| abstract | 1. A method of producing calcium carbonate with a reactively surface treated in an aqueous medium, which comprises the following steps: a) providing calcium carbonate; b) providing from 5 wt.% To 50 wt.%, Based on the weight of calcium carbonate, at least , one acid with a pK value of less than or equal to 2.5, where the anion of the corresponding acid is capable of forming water-insoluble calcium salts; c) providing gaseous CO; d) providing at least one water-soluble non-polymer organic th and / or inorganic weak acid and / or acid salt of said at least one water-soluble non-polymeric organic and / or inorganic weak acid; and e) contacting said calcium carbonate with said at least one acid with a pK value of less than or equal to 2.5 according to step b), with said gaseous CO according to step c) and with said at least one water-soluble non-polymer an organic and / or inorganic weak acid and / or an acid salt of said at least one water-soluble non-polymeric organic and / or inorganic weak acid according to step d); where at least one water-soluble non-polymeric organic Hepatic and / or inorganic weak acid has a pK value of more than 2.5, and where the anion of the corresponding acid is capable of forming water-insoluble calcium salts. 2. The method according to claim 1, in which at least one acid in which the pK value is less than or equal to 2.5, is selected from the group consisting of strong acids in which the pK value is less than |
