How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

The possibility of producing proppants from ferroalloy production waste (RFKh and VUFKh slags) using liquid glass and a polymer coating (PVA) was investigated. It was found that VUFKh slag, rich in strength-forming phases (90.5%), is the most promising raw material. Proppants obtained from VUFKh slag achieved standard sphericity values, but do not meet the requirements of GOST 54571-2011 for crush resistance (20% excess of the standard) and solubility in HCl. The technological feasibility of producing magnesium silicate proppants, suitable for use in medium-pressure reservoirs, has been substantiated, with the need for furtheroptimization of the mixture composition and firing regime to achieve full compliance with GOST. The use of this waste is recognized as economically viable.
