本文对产于俄罗斯希宾地区的单斜星叶石进行了不同的温度条件下的穆斯堡尔光谱效应研究,通过在温度分别在298 K,180 K和80 K条件下的分析,发现单斜星叶石由2个Fe~(2+)和1个Fe~(3+)四极双峰组成,并进行了单斜星叶石中的畸变参数包括八面体键角(σ~2)和键长变量(Δ)的计算。但是,在两个畸变参数之间存在着明显的差异,将无法对它们的穆斯堡尔参数和四极双峰进行指派。本文对温度在同质异能位移和四极分裂中的作用进行了探讨,根据通过穆斯堡尔效应和f(Fe~(3+)(O))/f(Fe~(2+)(O))的平均值获得的三价铁对全铁的比值,改写了单斜星叶石的化学式。
In this paper, we study the Mossbauer spectral effect of monoclinic asparagus produced in Russia’s Hibbing region at different temperatures. Based on the analysis of the temperature at 298 K, 180 K and 80 K, we find that the single Inclinite stone is composed of two Fe 2+ and one Fe 3+ quadrupole double peaks, and the distortion parameters in the monoclinic asparagus include the octahedron bond angle (σ 2) And key length variable (Δ) calculation. However, there is a clear difference between the two distortion parameters that will make it impossible to assign their Mössbauer parameters and quadrupole bimodals. In this paper, the effect of temperature on displacement and quadrupole isomorphism is discussed. Based on the results of Mossbauer effect and f (Fe ~ (3 +) (O)) / f (Fe ~ (2 +) O)) obtained from the average of the ratio of ferric to total iron, rewritten the formula of monoclinic asparagus.
