Phlogopite Mica Under Acidic and Alkaline Conditions: Reactivity and Silicate Gel Formation

Journal of the American Ceramic Society, Volume 109, Issue 6, June 2026.
ABSTRACT Alkali‐activated materials (AAMs) produced using industrial residues offer a sustainable alternative to Portland cement, the production of which contributes nearly 8% of global CO2 emissions. However, commercial sodium silicate, commonly used as an activator, remains costly and energy‐intensive to produce, motivating the development of ...

Effective Removal of Fe and Ca From Coal Fly Ash for High‐Purity and High‐Surface‐Area Zeolite X Synthesis: A Comparative Study of Acid Refluxing and Acid Roasting Methods

ChemistryOpen, Volume 15, Issue 5, May 2026.
Coal fly ash (CFA) is an abundant industrial waste rich in silica and alumina and represents a viable feedstock for zeolite synthesis; however, high levels of calcium and iron limit zeolite purity and crystallisation. This study evaluates acid refluxing and acid roasting as pre‐treatment strategies for the simultaneous removal of Ca and Fe from high ...
