ABSTRACT

Formation behavior of aragonite precipitated calcium carbonate was investigated with changed the concentration of Na2CO3 solution and addition method which added in the Ca(OH)2 slurry at 75oC. In this reaction, we found that Na+ ions were substituted into Ca2+ ion site then disturb the growth of calcite, and while proceed the crystal growth in a certain direction and promote the formation of aragonite. Also, a decrease of reaction rate by control the concentration of CO32- ion, induce the homogeneous precipitate reaction and increase substitution ability of Na+ ions, consequently it was promote the formation and growth of aragonite.
