摘要

PURPOSE: A method for manufacturing calcite is provided to adjust the particle size of crystallized calcite into a nano size by adjusting the concentration of a sodium hydroxide aqueous solution.;CONSTITUTION: A sodium hydroxide aqueous solution and a calcium chloride aqueous solution are prepared. The calcium chloride aqueous solution is slowly added into the sodium hydroxide aqueous solution at the room temperature and the atmospheric pressure. The sodium hydroxide is crystallized into calcite by blowing carbon dioxide gas. Solid and liquid are separated from crystallized slurry, and the solid is dried to obtain high purity calcite. The particle size of the calcite is adjusted according to the concentration of the sodium hydroxide aqueous solution and the calcium chloride aqueous solution.;COPYRIGHT KIPO 2012
