Impurity Composition of the High-Purity Glass Samples in the Exhibition-Collection of Extrapure Substances

摘要

In this paper, we discuss general aspects of the impurity composition of high-purity glass 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 high-purity oxide and nonoxide glasses of various systems and the statistical characteristics used to describe it.
