Abstract: The synthesis of zeolite P by like-solid phase method was studied, using silicon aluminum xerogels as silicon source and aluminum source, and the sodium hydroxide as the alkali source. The products were characterized and analyzed by methods such as X-ray diffraction (XRD) and scanning electron microscopy (SEM). The results showed that the zeolite P product with uniform morphology and good crystallinity can be prepared, when the nSiO2/nAl2O3 of the silicon aluminum xerogels was 5, the crystallization time and crystallization temperature were 3 h and 140℃, and the nNa2O/nSiO2 and nH2O/nSiO2 of the raw material were 0.26 and 18.51, respectively. Compared with the traditional hydrothermal method, the like-solid phase method greatly reduces the amount of water used in the synthesis process, shortens the crystallization time, improves the ion exchange performances of Ca2+ and Mg2+, and overall optimizes the synthesis process of zeolite P.
