THE EFFECT OF DRYING METHODS ON THE TEXTURAL PROPERTIES OF THE PSEUDOBOEHMITE SYNTHESIZED BY HOMOGENEOUS PRECIPITATION

摘要: Pseudoboehmite was prepared by using basic aluminum sulphate as a raw material, which synthesized homogeneous precipitation. This BAS neutralized in solid/liquid reaction with ammonium hydroxide order to transform hydroxide. The dried three different routes: spray drying, freeze and oven drying. effect of the drying methods on final textural properties heat treated pseudoboehmite evaluated. Spray best route obtain high surface area ( ) g m
