High purity sodium aluminate was prepared with sodium aluminate solution by adopting a process consisting of evaporation, cooling crystallization, and dewatering for purification. The effects of additives on caustic ratio and crystallization products, as well as the function and behavior of sodium aluminate solution during evaporation and crystallization were studied. The results show that with NaOH as an additive, the caustic ratio of the solution system can be increased, and the product from evaporation and crystallization can be converted to NaAlO2. By using NaAlO2 as seed crystal and adjusting the caustic ratio of system to 1.36 with NaOH, the product of NaAlO2 with purity of 88.1% can be obtained after evaporation at 100 ℃ for 2 h with stirring rate of 300 r/min. Then, after 1 h dewatering at 200 ℃ and 1 h purification with alcohol at 100 ℃, a kind of solid NaAlO2 can be obtained with purity of 93.8% and crystal particles of 5-25 μm.
