本文通过透射电镜研究了石墨—SbCl5层间化合物(简称SbCl5—GIC)的结构,由相对强度和级数的关系提出了堆垛模式。从 SbCl5-GIC的电子衍射花样得出: SbCl5以六方结构的α和β相以及外延生长的γ-相形式层间到碳层层面之间,其中aα=aβ=15. 15A,aγ=17.22A;aγ与 ac一致,而 aα和aβ相对ac转动±16°。 衍射斑点强度表明γ-相在一级SbCl5-GIC中含量最高,而在二级和三级中含量相近,而二级的电导率最高。γ-相是影响电导率提高的主要因素,γ-相含量越高,则它的电导率越低。
In this paper, the structure of graphite-SbCl5 intercalation compound (referred to as SbCl5-GIC) was studied by transmission electron microscopy. The stacking mode was proposed by the relationship between relative intensity and series. From the electron diffraction pattern of SbCl5-GIC, SbCl5 was deposited in the hexagonal α and β phases and the epitaxially grown γ-phase layer to the carbon layer with aα = aβ = 15. 15A, aγ = 17.22A; aγ coincides with ac, while aα and aβ rotate ± 16 ° relative to ac. The diffraction spot intensity shows that the content of γ-phase is the highest in the first grade SbCl5-GIC, while the content is similar in the second and third grades, while the second grade has the highest conductivity. The γ-phase is a major factor that affects the conductivity increase. The higher the γ-phase content, the lower its conductivity.
