Impurity composition of high-purity simple solids (elements) of group 13–16 Mendeleev periodic system

Resumo

This paper discusses correlations in the impurity composition of the purest solid group 13–16 elemental substances so far, exemplified by a set of samples in the Exhibition–Collection of Extrapure Substances, a permanent exhibition. The abundance of particular elemental impurities in the samples of the high-purity substances has been determined. Dividing the entire set of impurities into classes, we have accurately determined integral characteristics (average and total concentrations) of impurities in the samples and evaluated the contribution of each impurity class to the total impurity concentration.
