Abstract
This paper summarizes results of studies aimed at developing physicochemical and scientific methodological principles of the preparation of high-purity substances by integrated technological processes. We rely on the identification and chemical transformations of impurities in the recovery from raw materials, synthesis, and ultrapurification of substances by various methods. A scientific methodological approach has been developed for choosing and substantiating integrated processes for the preparation of extrapure-grade (6N or 7N) compounds with a total content of trace impurities from 0.1 to 1 ppm by weight from standard and unconventional raw materials. We have obtained batches of high-purity arsenic- and gallium-containing substances and tested them in the technology of advanced microelectronic and optical materials.
