, the loss of soda is mainly caused by the formation of sodium hydrate alumino-silicate. Based on the thermodynamic analysis of the reaction law between sodium hydrate alumino-silicate and hydrogarnet, it is found that hydrogarnet with more amount of SiO2 (x>1) can not be decomposed by caustic solution easily, while hydrogarnet with x<0.5 can be decomposed into sodium hydrate alumino-silicate......
