METHOD FOR PRODUCING ARAGONITE TYPE CALCIUM CARBONATE WITH HEXAGONAL PLATE FORM

摘要

PROBLEM TO BE SOLVED: To provide a method for producing calcium carbonate with a hexagonal plate shape by using a soluble calcium salt aqueous solution, a soluble carbonate aqueous solution and a surfactant and to provide calcium carbonate with the hexagonal plate form as a functional additive for a resin, a rubber, a coating material, papermaking, cosmetics and the like.;SOLUTION: Aragonite type calcium carbonate with the hexagonal plate form is produced by the method that the surfactant is dropped into the soluble calcium salt aqueous solution and the soluble carbonate aqueous solution so as to have a concentration above the micelle concentration and reacted at 40°C or higher.;COPYRIGHT: (C)2009,JPO&INPIT
