    • PURPOSE: A carium carbonate fabricating method is provided which is capable of fabricate carium carbonate with the high yield by precipitation of an urea and a cerium precursor in a continuous effector. CONSTITUTION: A carium carbonate fabricating method using precipitation of a mixture of an urea and a cerium precursor comprises the steps of: (a) adjusting the temperature of the urea or the mixture of the urea and the cerium precursor into 50~150 degrees Celsius; and (b) introducing (a) the urea and cerium precursor to a continuous effector(104). In step (a) the carium carbonate is manufactured in a orthorhombic crystal structure by controlling the temperature of all the urea or the urea and cerium precursor into 50~100 deg C each.
    • 目的:提供一种碳酸铯制造方法,其能够通过在连续效应器中沉淀尿素和铈前体而以高产率制造碳酸铯。 构成:使用尿素和铈前体的混合物沉淀的碳酸铯制造方法包括以下步骤:(a)将尿素或铈前体的混合物的温度调节至50〜150摄氏度; 和(b)将(a)尿素和铈前体引入连续的效应物(104)。 在步骤(a)中,通过将所有尿素或尿素和铈前体的温度分别控制在50〜100℃,制成斜方晶晶体结构。
