摘要
讨论了在多相反应系统中反应温度、CO2 浓度和搅拌速度等对沉淀 Ca CO3晶型和粒径的影响。测定了反应过程中碳化率和电导率的相关变化。实验表明 ,在 30°C以下可获得立方体 Ca CO3沉淀 ,在 30°C以上可获得纺锤型 Ca
In multi phase reaction systems the crystal type and particle size of precipitated CaCO 3 influenced by reaction temperature, concentration of CO 2 and stirring rate are discussed. The variation of carbonation rate and electric conductivity of the reaction solution were measured in reaction process. This experiment shows that it can obtain cubic type CaCO 3 below 30°C and spindle type CaCO 3 over 30°C.
