Synthetic Calcium Aluminosilicate Monolith: Transformations in an Aqueous Medium

Abstract

Investigations of the evolution of the phase composition, texture, and physical properties of SCAS monoliths with a set of spectroscopic, diffractometric, and thermal methods have shown that during the leach test an amorphous phase is accumulated and its composition changes. This is beneficial as regards stability of SCAS monoliths to the action of hydrosphere and makes them promising materials for the manufacture of matrices for immobilization of hazardous (toxic) wastes.
