英文摘要	For the deep removal of silica from sodium aluminate solution with a high alkaline concentration, we propose novel ferrite desilication reagents calcium hydroferrocarbonate (CHFC; 3CaO.Fe2O3.CaCO3.12H(2)O) because Fe3+ cations show extremely low solubilities of similar to 1-3 mg/L in highly concentrated caustic solutions. The main factors affecting the synthesis of CHFC were studied, including time, temperature, liquid-to-solid mass ratio, and particle size of CaO. The results showed that CHFC is a metastable material in the alkaline solution, and the synthesis factors, time and temperature, are related to each other. The optimum synthesis conditions of CHFC were determined. The mechanisms in the synthesis of CHFC, and the desilication mechanism by CHFC, are discussed, using the desilication reaction and X-ray Diffraction analysis. In the desilication process, silica combines with CHFC to form calcium hydroferrosilicate, calcium hydroferroaluminosilicate and.calcium ferroaluminosilicate.
