Pseudo-boehmite ke selelekela se setle ka ho fetisisa nakong ea tlhahiso ea gamma alumina, hobane ho hlokahala feela ho tlosoa ha metsi ka calcination hoo e ka bang 447 C. Taolo ea liphetoho tse sebetsang nakong ea tlhahiso ea pseudo-boehmite: supersaturation ea litharollo ke ntlha ea bohlokoa bo ikhethang, ho phaella moo pH, mocheso, litšila le mofuta oa li-reagent [3,4]. Netefatsa bohloeki ba thepa ena 'me liphetoho tsena li khetholla sebopeho, sebopeho le sebopeho sa eona sa precipitate. Ka hona, ho bohlokoa ho latela liketsahalo tse etsahalang nakong ea tlhahiso, e le ho bolela esale pele chai le boleng ba sehlahisoa sa ho qetela. Mosebetsing ona, tlhahiso ea pseudo-boehmite e ntlafalitsoe ka mokhoa oa pula, ho sebelisoa tharollo ea aluminium sulfate supersaturated ea maemo a indasteri le ammonium hydroxide e matlafalitsoeng (28%) e le li-reactants; mokhoa ona o tsejoang o ntlafalitsoe ho fokotsa mocheso oa karabelo ka tlase ho ntlha ea ho belisa ea ammonia. Taolo ea mocheso oa mecha ea reactant e fihletsoe ka ho fumana data le ho laola ka boiketsetso mecha ea ho futhumatsa. Ho bontšitsoe hore ho sebetsa reactor maemong a isothermal ho netefatsa boleng ba ho qetela ba pseudo-boehmite e hlahisoang.
