Abstract: A new device was designed, which can effectively avoid the undesired nucleation and agglomeration of fineparticles 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 Na2O (Nk)170 g/L, the mole ratio of Na2O to Al2O3(αk) all between 1.52 to 2.01, at 65, 70, 75℃, respectively. And the kinetics equation of crystal growth of gibbsite was deduced.
