Outline of a Washing Treatment to Improve Electric Arc Furnace Slag Environmental Behavior
steel research international, Volume 97, Issue 5, Page 2541-2558, May 2026.This study evaluates a water‐washing treatment for electric arc furnace slag to reduce the leaching of hazardous elements (Cr, Ba, Mo, and V), enabling its reuse. The process effectively decreases leachate concentrations. Using the treated slag as a substitute aggregate in concrete reduces greenhouse gases emissions by 42.5% compared to landfilling ...

Chromite placer occurrences of the Volga-Ural basin – genesis, sources and industrial potential
GeoresursyChromium is a strategic metal, but more than a half of Russia’s needs are met by imports, so new deposits of chromites, including unconventional placer deposits, are of industrial and scientific interest. Previous studies and current works of the authors

Alkali Vapor Corrosion of Spinel (MgAl2O4) and Gahnite (ZnAl2O4) Refractories—A Comparative Study
Journal of the American Ceramic Society, Volume 109, Issue 5, May 2026.ABSTRACT Alkali vapor corrosion is critical for refractories used in the kilns and furnaces of diverse high‐temperature processing and manufacturing sectors such as gasifiers, cement production, and glass making. Gahnite (ZnAl2O4) is being investigated as a potential chrome‐free refractory because of its similarity with the structure and properties of ...
