The said process comprises the mixing of sodium carbonate (Na2CO3) with CWM in the ratio 1: X (X=0.3-1.5).The mixture was fused in the temperature 800 C for 2hrs with ramping rate of 1 C/min. Then fused mass was acid treated, followed by washing and an appropriate amount of water, and TPAOH was introduced into this and then placed for aging for 24-48hrs and; after that the material obtained was placed for crystallization for 60 to 120 hours. After crystallization, the mother solution was filtered and dried and then calcined at 550 C for 4hrs with a ramping rate of 1 C /min."
