© 2018 The coarse agglomerates of gibbsite (γ-Al(OH)3) are grateful starting materials for preparation aluminum oxides and hydroxides as boehmite and γ-Al2O3, which are extensively used as a catalysts and catalyst support ...

© 2018 by the authors. The presence of χ-Al2O3resulting from thermal decomposition gibbsite as part of alumina catalysts is unfavorable because of its acid characteristics. One of the available techniques of χ-Al2O3removal ...
