In order to investigate the synthetic possibility of the zeolite X using detergent builder from dickitic agalmatolite, synthetic reactions were studied with variables such as mole ratios of reactants and reaction time. The alkalinity of reaction mixtures have greatly influenced in the composition and the particle size distribution of zeolite X. Then the average size of the zeolite particles obtained has to be adjusted through the H2O/ Na2O mole ratios. The SiO2 /Al2O3 mole ratios as low as possible led to zeolite X with high crystallinity. Increasing the Na2O/ SiO2 mole ratios, the velocity of crystallization was advanced. The synthesis of zeolite X from a calcined agalmatolite and sodium silicate solution was possible at lower price for its use as a builder in detergents. Optimized aging time was 12 hours with increase in the nucleation of amorphous gel which enhances its reactivity. This effect is lower as the aging time increases.
