Sažetak
Solid phase (X-ray amorphous aluminosilicate) separated from the hydrogel having batch composition 3.23 Na2OˇAl2O3c1.93 SiO2c128 H2O, was calcined at different temperatures (100-800oC) for 1h and then transformed into zeolite A by heating in a 2M NaOH solution at 80oC. Analysis of the precursors and products (zeolite A) has shown that the calcination of the precusor decreases the concentration of nuclei in the gel matrix and hence influences the particulate properties of the zeolite obtained during the hydrothermal treatment of the precursors.
