| titleOfInvention | Calcium carbonate manufacturing method |
| abstract | PROBLEM TO BE SOLVED: To provide a method for producing calcium carbonate having a controlled form while efficiently utilizing carbon dioxide gas. The following steps: a carbon dioxide gas absorption step of absorbing carbon dioxide gas in a sodium hydroxide aqueous solution having a concentration of 5 to 20% to obtain a sodium carbonate aqueous solution having a concentration of 6 to 24%; calcium oxide and water. To obtain lime milk, which is a suspension of calcium hydroxide having a BET specific surface area of 5 to 40 m 2 / g, in a hydration step; the reaction is carried out by adding the sodium carbonate aqueous solution to the lime milk. It is a method for producing calcium carbonate, which comprises a carbonation step and; [Selection diagram] Fig. 3 |
