ABSTRACT:
Disclosed is a process for producing aragonite crystal form calcium carbonate with an acicular shape characterized by premixing aragonite crystal calcium carbonate and Ca(OH).sub.2 to prepare an aqueous slurry, adding a water-soluble phosphoric acid compound into the aqueous slurry, and introducing CO.sub.2 gas into the aqueous slurry to cause the carbonation reaction to take place. According to the present invention, aragonite crystal form calcium carbonate in an acicular shape with a large particle size is produced.
