Abstract

PURPOSE:To easily obtain spherical pure baddeleyite type calcium carbonate suitable for additive in coating, etc., having excellent dispersibility, etc., by adding amino acid (salt) to aq. suspension of calcium hydroxide and by blowing in carbon dioxide. CONSTITUTION:The aq. suspension of calcium hydroxide is added with amino acid or salt thereof (e.g. glycine, sodium glutamate) and thereafter, is taken part in carbonation by crushing, the baddeleyite type calcium carbonate is produced. The amt. of amino acid (salt) to be added is preferably in the weight ratio of 1/5-1 to the weight of calcium hydroxide. It is necessary that the ratio of blowing in carbon dioxide is >=5ml/min per 1g calcium hydroxide, expressed in terms of pure carbon dioxide, and the period from the start to the end of the neutralization reaction is within 90min.
