生成稀土氧化物所需要的条件是什么?为什么在氧硫化合物类型夹杂物中富集(钅兰)?为什么钢中各种类型的稀土夹杂物有明显的生成顺序?对于现有的各种稀土化合物标准生成自由能数据进行分析研究,有可能在有关稀土元素同氧、硫及白色金属的反应方面,作出某些预洲。大多数的结果,同理论上的预测是相符的。但是,另一些预测似乎是错误的,甚至有一些观察到的反应,仅仅分析研究标准生 What are the conditions required for the formation of rare earth oxides? Why is it enriched in sulphide type inclusions (钅))? Why is there a clear order of occurrence for all types of rare earth inclusions in steel? For all available rare earths It is possible to make some predictions regarding the reaction of rare earth elements with oxygen, sulfur and white metals by analyzing the standard free energy data of the compounds. Most of the results, with the theoretical prediction is consistent. However, other predictions seem to be wrong, and there are even some observed responses that simply analyze the standard of study students
