The Granat-2M growth facility has been updated for synthesizing different quartz glasses by the "gas -vacuum in vacuum" scheme. Its prototype is a commercial facility used for floating ultrapure monomineral and doped quartz glasses by the KS-4V glass production technology.
The composition of mineral inclusions in quartz sand of wastes from kaolin production at "Plast-Rifei," operating at the Zhuravlinyi Log deposit, is studied. Different technological operations for enriching this raw material are tested. It is shown that the use of different technological operations for enriching wastes and using them to develop high-purity quartz concentrates suitable for the fabrication of glass is an effective procedure.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
