Impurity Composition of High-Purity Solid Halides

Abstract

In this paper, we discuss general aspects of the impurity composition of high-purity solid halides, which are exemplified by an array of samples in the Permanent Exhibition–Collection of Extrapure Substances. We estimate the average and total concentrations of elemental impurities in the purest samples and assess the contributions of individual impurity classes to the total impurity concentration, which makes it possible to more accurately characterize the impurity composition of solid halides and statistic characteristics used to describe it.
