영문 초록

This research is focused on an improvement of additional value of high grade limestone. To obtain the basic data of precipitated calcium carbonate(PCC), studies of physical properties of limestone, calcination and hydration characteristics, the characteristics to manufacture quick lime, hydrated lime, ground calcium carbonate and precipitated calcium carbonate were performed. In the carbonation process, formation of rombohedral must be kept under 10℃ for reaction. Although the temperature of reaction of lime milk was limited under 30℃ for a colloidal PCC manufacture, over 50℃ for spindle type PCC. The recommended reaction conditions for colloidal PCC are 20℃ of reaction temperature, 4% of Ca(OH)₂ concentration, 1000rpm of stirring rate and 200ml/min of CO₂ gas flow rate.
