Characterization of Gel Layers Formed on Alkali‐Modified Aluminoborate Glasses During Aqueous Corrosion

Journal of the American Ceramic Society, Volume 109, Issue 6, June 2026.
ABSTRACT The nature of gel formation on borate glasses during dissolution remains relatively unexplored, despite relevance to bioactive glass applications. In this work, we investigate gel‐layer formation on sodium‐ and potassium‐ modified aluminoborate glasses after dissolution in deionized water.

Inclusions Size Distributions After Calcium Treatment in Low Carbon Aluminum Killed Steels

, 2018
This work addresses conflicting results shown in the literature regarding liquid inclusion agglomeration. It has been shown that liquid calcium aluminates do agglomerate and hence change in size over time.

Dynamics and Structure of Molten Neodymium Titanate

Journal of the American Ceramic Society, Volume 109, Issue 6, June 2026.
ABSTRACT Binary rare earth titanates can be vitrified using levitation melt quenching, and their glasses are promising for optical applications. To better understand their thermophysical properties and dynamics, we have used molecular dynamics (MD) and empirical potential structure refinement (EPSR) to simulate molten neodymium titanate, 83TiO2–17Nd2O3.

Co‐Calcination of Silicate or Aluminosilicate Network of Clay and Non‐Clay Minerals With NaOH: Physicochemical Insights

Journal of the American Ceramic Society, Volume 109, Issue 6, June 2026.
Effects of co‐calcination with alkali hydroxide on pure clay minerals (kaolinite, montmorillonite) and typical impure minerals (quartz, feldspar) are presented. Co‐calcining montmorillonite and quartz with sodium hydroxide improves their reactivity. Co‐calcining kaolinite with sodium hydroxide reduces its reactivity.

Reactions of fly ash with calcium aluminate cement and calcium sulphate

, 2009
The hydration processes in the ternary system fly ash/calcium aluminate cement/calcium sulphate (FA/CAC/C$) at 20 °C were investigated; six compositions from the ternary system FA/CAC/C$ were selected for this study.
