Ionothermal Synthesis of Sodalite from Metakaolin

Abstract:

The sodalite was prepared with metakaolin by the ionothermal method in deep eutectic solvent(choline chloride/urea). Such factors as the Na₂O/SiO₂ ratio, crystallization temperature and time had effects on the structure and property. The high crystallinity and purity of sodalite can be obtained at the Na₂O/SiO₂ ratio of 3:1, and the temperature of 180°C for 60h. The product was characterized by means of X-ray diffraction, Infrared spectrum and scanning electron microscopy.
