Abstract
A process for preparing crystalline boehmite includes combining a stoichiometric amount of flash calcined gibbsite (AIO) and gibbsite (Al(OH)) in a pressurizable reaction vessel; heating the flash calcined gibbsite and gibbsite in the reaction vessel to a temperature of about 200° C. to about 280° C. and for a time sufficient to form crystalline boehmite. A crystalline boehmite exhibiting a crystallite from about 600 Å to about 850 Å when measured in the 120 direction of the crystallographic space group Cmcm.
