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 ...
