Abstract: Using silica sol, aluminum sulfate, sodium hydroxide, deionized water as raw materials and N,N,N-trimethyl-l-adamantammonium hydroxide (R) as template, SSZ-13 molecular sieve was synthesized by traditional hydrothermal method. Factors affected the synthesis of SSZ-13 molecular sieve were investigated and the optimal synthesis conditions were obtained as follows: n(SiO2)/n(A12O3)＝40，n(Na2O) /n(A12O3)＝16，n(R2O)/n(A12O3)＝5，n(H2O)/n(A12O3)＝900，crystallizing at 155℃ for 3 days. The samples were characterized by XRD，SEM and FT-IR techniques. Results showed that sample obtained under the optimal conditions exhibited good crystallization and the time of crystallization was much shorter than reported. When promoter was added during synthesis the crystallization time could be further reduced to 2 days, indicating that the cost of synthesis was lowered.
