KINETICS OF SOLID-STATE MULLITE SYNTHESIS FROM ACTIVATED PRECURSORS
Abstract
The solid-state synthesis kinetics of the mullite 3Al2O3∙2SiO2 from aluminium hydroxide and metasilicic acid was studied. Hydrated oxides obtained in an active form as a result of a mechanical activation or co-precipitation (precursors) were subjected to a high-temperature treatment. The reaction rate was described by the kinetic first-order equation. Effective rate constants and energy activation were determined. The positive action of mullite seed crystals on the product accumulation was confirmed.
