The samples of Sn4+ zeolite are obtained by cation exchange between natural zeolite and SnCl4, and then treated at different Temperatures (70-1000℃). By using Mossbauer spectroscopy, X-ray diffraction and infra-red spectroscopy, we studied the change of position of Sn4+ in the zeolite structure with the temperature. The results show that the Sn4+ is situated in the main duct (channel) of the zeolite structure, but with the increase of the temperature the zeolite is dehydrated gradually, then the Sn4+ begins to move from the center of the duct to the walls of the duct, consequently, owing to the increase of the asymmetry of the electric field where the Sn4+ is situated, the quadruple splitting increases with the increase of the temperature. At the same time the SnO2 component increases with the increase of temperature. When heat-treatment temperature reached 1000℃ the long range order structure of zeolite may be destroyed completely.
