sodium aluminate solution%seeded precipitation%crystal growth%kinetics
A new device was designed, which can effectively avoid the undesired nucleation and agglomeration of fine particles on the experimental results during the seaded precipitation of sodium aluminate solution, and moreover, the experimental conditions are nearly kept constant during the experiment. With the new device, it is proven that a good result can be obtained on the kinetics study of the crystal growth in seeded precipitation of sodium aluminate solution. Experiments were carried out with the concentration of Na2 O (Nk)170 g/L, the mole ratio of Na2 O to Al2 O3 (αk) all between 1.52 to 2.01, at 65, 70, 75 ℃, respectively. And the kinetics equation of crystal growth of gibbsite was deduced.
