近年来人们对混合价化合物的研究十分关注,已发现的这类化合物主要是稀土元素的金属化合物。最近笔者在研究稀土化合物的电子能谱时观察到,固态硫酸铈(Ⅳ)也是一种混合价化合物(或称波动价化合物),而且铈的价态与温度有关,还发现硫酸缔的热分解行径与文献报道有很大出入。 In recent years, people are very concerned about the study of mixed valence compounds, which have been found to be mainly rare earth metal compounds. Recently I observed in the study of the electronic spectrum of rare earth compounds, solid state cerium (IV) is also a mixed valence compounds (or valence compounds), and valence of cerium and temperature, also found that the thermal decomposition of sulfuric acid There are a lot of discrepancies between the behavior and the literature.
