Abstract：On the basis of preparation of light －duty calcium carbonate in traditional method，additives are used to control the particle size of calcium carbonate．The superfine calcium carbonate is synthesized by chemosynthesis．T he effects of capacity for additives，the time for adding，the initial concentration of Ca（OH）₂，the percentage of CO₂，the speed of stir on the synthesis of calcium carbonate and the particle size are investigated， and the synthesis principle is also studied．
