摘要: PROBLEM TO BE SOLVED: To provide a method for producing nano-sized calcium carbonate. SOLUTION: Carbon dioxide is blown into 0.5-4 mass% aqueous suspension of hydroxide at an initial temperature 0-25°C, while irradiating the with ultrasonic wave not less than 20 kHz. The irradiation may be performed using single generation source or plurality sources. generating particularly limited. When waves, combined use those Langevin type and horn preferred.
