摘要: A simple one-step method for the preparation of NaA zeolite spheres using a nonhydrothermal process is introduced in this article. The mechanism formation was studied by suspension solidification both silicone oil and polyethylene glycol. crystalline phase, micromorphology, microstructure produced were characterized X-ray diffraction (XRD), scanning electron microscopy (SEM), BET specific surface tests. results demonstrate that geopolymer can directly transform into but not glycol (PEG). Since PEG cannot retain water spheres, there no additional medium transport rearrange aluminate silicate groups gel. Thus, gel crystallize to form crystals.
