ABSTRACT:
Crystalline materials having increased mechanical strength and improved chemical properties are provided by incorporating carbonate by contact treatment with carbon dioxide (CO.sub.2) to modify the alkaline earth oxide morphology. Alkaline earth-containing particulate solids are stabilized in the crystalline oxide structure, preferrably with dense phase or supercritical CO.sub.2. Typical industrial applications include particulate contact solids, catalysts, binders and monolithic structures.
