| Abstract: | The non crystal Fe 2O 3 SiO 2 hybrid material was prepared by sol gel process, using tetra ethoxy silane(TEOS) and FeCl 3 as start materials. The electric properties of sol gel system was studied and the hybrid mechanism of Fe 2O 3 SiO 2 material was explored.The structure and properties of the hybrid material were characterized and tested respectively.The material possesses excellent properties of spectrum absorbing selectively,and can be used for solar thermal conversion. |
