摘要
研究了NaCl-CaCl2对氧化钙分解独居石的热分解过程的影响,表明,NaCl-CaCl2的加入,使氧化钙分解独居石的分解温度降低。在此基础上研究了NaCl-CaCl2的加入量、焙烧温度和焙烧时间对氧化钙分解独居石分解率的影响,结果表明,NaCl-CaCl2的加入量为10%、焙烧温度750℃、焙烧时间1h的条件下,氧化钙分解独居石的分解率可达到79%。
Influence of NaC1--CaCl2 on thermal decomposition of monazite with CaO is studied. The monazite is decomposed with CaO at lower temperature because of adding NaC1--CaCl2. On this basis, Influence of addition of NaC1--CaCl2, roasting temperature and roasting time on decomposition rate of monazite with CaO is studied. The results show the decomposition rate of monazite with CaO is 79% when the addition of NaC1--CaCl2 is 10%, the roasting temperature is 750℃ ,and the roasting time is lh.
