摘要：

The effect of the initial mixture composition and crystallization conditions (temperature and time) on the molar ratio SiO2/Al2O3 Of mordenite has been investigated. The obtained SiO2/Al2O3 molar ratio in mordenite is directly proportional to the initial mixture (SiO2/Al2O3 x Na2O/H2O) composition, always being lower than that. The obtained values increase and tend to approach the initial value only with increasing crystallization temperature and time. The calculated activation energy value for incorporation Of SiO2 into the mordenite lattice is very close to that of crystallization.
