clear liquid phase initiating agent with transparency>75% and life time up to 10 days was obtained by adding some waterglass to common initiating agent and its life time was prolonged as the SiO2/Al2O3molar ratio of the added waterglass decreased. As compared with common initiating agent, the NaY zeolite synthesized with clear liquid phase initiating agent has small particle size between 0. 1 ￣0. 3μm, lower DTA destroy temperature and approximately equal structural SiO2/Al2O3 molar ratio, surface area and micropore volume. Besides, the particle size of NaY zeolite synthesized with a mixed initiating agent composed of common and clear liquid phase initiating agents was between those with two initiating agents independently.
