Influence of Processing Variables on the Hydrothermal Synthesis of Zeolite–Geopolymer Aggregates from Kaolin

Journal of the American Ceramic Society, Volume 109, Issue 7, July 2026.
ABSTRACT This study addresses the influence of key processing variables on the hydrothermal alkaline treatment of low‐temperature fired kaolin‐aggregates for the development of zeopolymers (zeolite–geopolymer composites). Parameters such as hydrothermal treatment temperature (90 and 150°C), reactor volume (250 and 500 mL), liquid‐to‐solid (L/S) ratio ...
