AbstractBayerite was synthesized successfully by the precipitation reaction of a sodium aluminate solution with sodium bicarbonate in a mixed suspension mixed product removal (MSMPR) crystallizer. The particle size distribution of the prepared bayerite was significantly influenced by the temperature, the stirring speed, and the molar ratio (MR) of Na2Oc/Na2Ok as well as the addition rate of aqueous NaHCO3 solution in the system. The uniformly spherical bayerite with narrow "missing-fines-type" particle size distribution was obtained at 50 degrees C, with the MR of 0.66, at the agitation speed of 300 rpm in the MSMPR crystallizer. The synthesis of bayerite from the reactive NaAl(OH)(4)-NaHCO3 system was without an aging process. The thermal decomposition of the prepared bayerite was analyzed by TGA/DSC and XRD.
