    摘要: Disclosed is a novel process of producing plate-shaped calcium carbonate particles. The process comprises the steps of adding aqueous calcium hydrogen carbonate solution with a temperature of less than 50°C into an aqueous medium bath held at a temperature of not less than 50°C to generate plate-shaped calcium carbonate particles in the bath, the temperature of the bath being kept not less than 50°C during the addition of the aqueous calcium hydrogen carbonate solution; and recovering the generated plate-shaped calcium carbonate particles.
