ABSTRACT:
A silica-containing bayerite alumina is prepared by reacting aluminum sulfate, sodium aluminate and sodium silicate at a pH of about 10.5 to 11.5, preferably in the presence of finely divided magnesium hydroxide "seeds". The silica-containing bayerite is heated to obtain a hydrothermally stable silica "stabilized" eta alumina which may be used in the preparation of catalytic compositions.
