- zeolites are microporous crystalline materials formed by a crystalline network of T0 4 tetrahedra that share all their vertices giving rise to a three-dimensional structure that contains channels and / or cavities of molecular dimensions. They are of variable composition, and T generally represents atoms with a formal oxidation state +3 or +4, such as Si, Ge, Ti, Al, B or Ga, among others.
- T generally represents atoms with a formal oxidation state +3 or +4, such as Si, Ge, Ti, Al, B or Ga, among others.
- the existence of channels and cavities of regular dimensions inside the zeolites originates a high specific area. The fact that the pore size is uniform and with a narrow distribution, in these crystalline materials, allows selectively adsorbing molecules of different sizes depending on the dimensions of the channels.
- the crystalline structure of each zeolite results in a characteristic X-ray diffraction pattern. Therefore, the zeolites differ from each other by their range of chemical composition and their X-ray diffraction pattern. Both characteristics (crystalline structure and chemical composition) also determine the physicochemical properties of each zeolite and its possible application in different industrial processes.
