摘要
热力学计算结果表明,在450℃~750℃区间,可以用氯化钠作为氯化剂,对稀土氧化物进行加碳氯化。实验结果表明,借助累托石的制团作用,在动力学区间反应级数为2/3,符合界面化学反应的动力学特征。介绍了影响氯化反应的其他因素。
The thermodynamical computation of rare earth oxide with the addition of carbon has been investigated.It was shown that the chloridizing reaction can realize over the temperature range 450℃~750℃ in the presence of sodium chloride as the solid chlorizating agent.The experimental results have shown that,due to agglomeration of rectorite,the order of this reaction in the kinetic region was 2/3 in correspondence with the kinetic characteristics of the interfacial chemical reaction.The other factor of the effect on the chloridizing reaction has been introduced.
