Abstract: Isothermal phase transformation digram was developed for the K2O-Na2O-Al2O3-SiO2-H2Osystem at 100℃. T-type zeolite was obtained as a pure phase from the reaction mixture with the mole ratio as. 32>SiO2/Al2O3>24 0.34>M2O/SiO2>0.30 0.30>K2O/M2O>0.23 H2O/SiO2 = 16 In the induction period of T-type zeolite or amorphous phase region there were no spontaneous nucleation. Akinetic model on the crystal growth of rod-like T-type zeolite was suggested as dx/dt= kx2/3 , where k is related to the composition of original gel, especially to the temperature. Ec of T-type zeolite was measured as 16.7Kcal/mol for the system of 1.95K2O·5.85Na2O·Al2O3·26SiO2·416H2O.
