【摘要】 对以硝酸钠为氧化剂的富铈混合碳酸稀土焙烧过程进行了实验研究。通过对氧化剂加入量、焙烧温度、焙烧时间的考察 ,得出了铈氧化率的变化规律。研究结果证明 ,硝酸钠对铈的氧化作用是显著的。更多还原

【Abstract】 In the paper,sodium nitrate was taken to be an oxidant in the process of roasting rich cerium rare earth carbonate mixture.The research experiment got a change regulation of the oxygenate rate of cerium by investigaing the amount of the added oxidant,the roasting tempreture and the roasting time.It shows that the oxygenation of the sodium nitrate is obvious to cerium.更多还原
