AbstractThe decomposition of NaCaHSiO4 in sodium aluminate solution was investigated. NaCaHSiO4 transformed to sodalite and katoite during decomposition. Parameters, such as Na2O concentration, reaction time, temperature and Al2O3 concentration, had a significant influence on the NaCaHSiO4 decomposition. The optimal Na2O concentration and reaction time for the NaCaHSiO4 decomposition were 150 g/L and 105 min, respectively. The extent of NaCaHSiO4 decomposition largely depended on Al2O3 concentration in sodium aluminate solution. Reaction products were composed of thin flakes with a loose structure at 50 g/L of Na2O concentration, and were agglomerates with a compact surface composed of tabular and rod crystals at 150 g/L of Na2O concentration.
