Porous structure of aluminium hydroxide and its content of pseudoboehmite

Abstract The dependence of aluminium hydroxide porous structure on the content of pseudoboehmite in precipitates was studied. It was found that more crystalline wet material had a higher total pore volume as it resisted to a greater extent the influence of mechanical forces during centrifugation. No decrease in the effect of the capillary forces acting in the drying stage with an increasing amount of pseudoboehmite was observed.
