Morphology of zeolite a crystals synthesized at different alcalinity
The possibility to control particulate properties (particularly morphology) of the synthesized crystals can be implemented through several physico-chemical parameters. In this paper, we have studied the influence of the alkalinity of the system on the size and morphology of zeolite A crystals. Prepared hydrogels were heated at 80°C in reactors made of HDPE, under static conditions. Starting compositions were: 3.2/12.0 Na2O × 2 SiO2 × 1.1 Al2O3 × 300.0 H2O. The characterization of the samples was performed using several analytical methods such as: X-ray diffraction (XRD), laser light scattering (LLS), optical microscopy (OM) and scanning electron microscopy (SEM). The analysis of the results show that the increase of alkalinity of explored system had two major effects: increase of the number of nuclei (crystals) in system and formation of crystals with more irregular shape.
