The abrasive ability of a staurolite mineral concentrate of 160/100 grain size produced by Vilnohirsk Mining and Metallurgical Combine is determined and comparative data of the abrasivity of AC6 125/100 synthetic diamond powder is indicated. (Grinding powders of such grain size are most often used in abrasive grinding tools and pastes). The results of our studies of the abrasiveness of staurolite concentrate samples have shown that the staurolite can be used in compositions for the production of special types of tools and pastes intended to achieve high-quality surface treatment.
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.
