本文介绍了我们设计的微波加热氧等离子体炬的特点，并将其应用于金属氯化物热化学后处理转化为氧化物的方法中。为此，利用该等离子体装置对几种典型的金属氯化物进行了氧化实验，并计算了各金属氯化物和氧气体系的热力学平衡图。结果发现，我们的氧等离子体有可能实现这样的氧化反应，平衡图可以预测金属氯化物在氧等离子体中的氧化特性，根据氯化物的氧化难度，氯化物具有转化特性。最后，根据计算的热力学平衡图的预测结果，将氯化物分为三类。
In this paper we show the feature of the microwave heated oxygen plasma torch which we designed and apply it to the conversion method of metal chloride wastes in a pyrochemical reprocessing into oxides. For this purpose oxygenation experiments of several typical metal chlorides were carried out by using this plasma device and thermodynamic equilibrium diagrams of each metal chloride and oxygen system were calculated. Consequently, it was found that our oxygen plasma has a possibility to realize such a oxygenation reaction, the equilibrium diagrams can predict the oxygenation characteristics of metal chlorides by oxygen plasma and the chlorides have conversion characteristics according to their oxygenation difficulties. Finally, we classified chlorides into three categories by predictions from the calculated thermodynamic equilibrium diagrams.
