STRONTIUM-CATALYZED BOEHMITE FORMATION

A strontium-catalyzed process for preparing boehmite includes combining a strontium material, flash calcined gibbsite, and water to obtain an aqueous suspension; contacting the aqueous suspension with a water-soluble carbonate material; and heating the aqueous suspension to a temperature, and for a...

Beschreibung
Zusammenfassung:	A strontium-catalyzed process for preparing boehmite includes combining a strontium material, flash calcined gibbsite, and water to obtain an aqueous suspension; contacting the aqueous suspension with a water-soluble carbonate material; and heating the aqueous suspension to a temperature, and for a time, sufficient to form at least about 5 wt. % of boehmite.
