摘要: The calcium carbonate is prepared by: (a) slaking quicklime in an aqueous medium; (b) carbonating and neutralising the suspension of slaked lime formed step using a gas comprising carbon dioxide; (c) separating precipitated from medium which it suspended. There added 0,01 % to 15 by weight based on dry oxide, reagent having one or more active hydrogen atoms (or salt thereof), (a).
