　　For purpose of deeply depositing silica from high concentration of sodium aluminum solution, it is put forward to the uses of new desilication agent-the ferrite series compound, i.e.Calcium Hydroferrite, Calcium Hydroferrocarbonate, Calcium Hydroferrosulfate, for that Fe3+ cation has extremely low solubility characteristics (1~3mg/L) in high concentration caustic media.
