Process for the preparation of aqueous suspensions of alumina at least partially in the form of ultra-fine boehmite and their applications

摘要

the present invention relates to a method of preparation of alumina, at least in part, in the form of other ultra-fine boehmi.;according to a specific implementation of the invention.alumina, at least in part, in the form of ultra-fine boehmite is obtained by treatment in an aqueous medium having a ph less than 9 of an active alumina powder obtained by dryingrapid hydrargillite in a stream of hot gases.;the alumina obtained can be used as possible after drying and calcining, binder, thickener, dispersing.film forming, formation, membrannes, base material for catalyst support.
