This paper focuses on deciphering the gel aging temperature effect on the crystallization of zeolite rho(RHO). Increased gel aging temperature (from room temperature to 55°C and no aging) caused an increase in induction periods and decreased the crystallization rate during the synthesis of RHO. Other crystalline phases such as chabazite were formed along with increasing aging temperature. The largest crystal size of RHO increased proportionally to aging temperatures up to about 9 μm. These results suggest that aging temperature greatly affected the crystallization, the crystal sizes, the purity and the formed crystalline phases during the synthesis of zeolite rho. This study suggests that most of RHO nuclei are formed during gel aging and their formation is depressed by the increased aging temperatures.
