| titleOfInvention | Chromium(iii) carbonate and process for production of same |
| abstract | A chromium(III) carbonate which assumes a light blue color in a solid state. The chromium(III) carbonate exhibits an L* value of 50 to 70, an a* value of -4 to -2, and a b* value of -10 to -7, each value being defined in the L*a*b* color system (JIS Z8729). It is preferable that the chromium(III) carbonate is completely dissolved within 30 minutes when the chromium(III) carbonate in an amount corresponding to one gram of Cr is added at 25 DEG C to one liter of an aqueous hydrochloric acid solution having a pH of 0.2. The chromium(III) carbonate is produced preferably by bringing an aqueous solution of a carbonic acid salt into contact with an aqueous solution containing trivalent chromium under such conditions that the reaction fluid temperature falls within the range of 0 DEG C to lower than 50 DEG C and at a pH of 6 to 12. It is preferable that after the formation of chromium(III) carbonate, the reaction mixture is filtered and washed with water until the electric conductivity of the filtrate falls to 5mS/cm or below. |
