[0002] Sodium aluminate (NaAlO2) is an inorganic compound with the chemical formula NaAlO2. It is a white crystalline powder, hygroscopic, highly soluble in water, insoluble in ethanol, and its aqueous solution is alkaline. When preparing sodium aluminate, sodium aluminate, water and alkali are mixed together in a certain ratio, and then the slurry mixture is filtered to separate more water, and then the filtered solid material is dried to remove the remaining water to obtain a dry solid mixture. Finally, the dry solid mixture is sintered to make the solid mixture react chemically to generate sodium aluminate. When preparing sodium aluminate, most of the existing devices add sodium hydroxide solution too concentratedly when adding sodium hydroxide, and the sodium hydroxide solution is added from a certain place in the reaction container to the reaction container in a concentrated one-time manner, resulting in insufficient contact between bauxite powder and sodium hydroxide, uneven mixing, incomplete adsorption of sodium hydroxide by bauxite powder, and low conversion efficiency.
