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 ...

Potential of Saudi Arabian bauxite to produce low-carbon cement
CementTo produce calcium aluminate cement (CAC), bauxites are usually fused with lime/limestone at high temperature (1600 °C). At this temperature, the bauxite´s hydrates of alumina break down - dehydroxylation - and combine with calcium forming monocalcium ...

Enhancing the Reactivity of Dicalcium Silicate Using Aluminum and Sulfur Ions Co‐Doping
Journal of the American Ceramic Society, Volume 109, Issue 5, May 2026.ABSTRACT Belite‐rich cements are a lower‐energy and lower‐CO2 alternative to Portland cements, but the low hydraulic activity of belite remains a major limitation. This study explores the impact of aluminum and sulfur co‐doping on the structure and hydration of synthetic dicalcium silicate (C2S).
