Due to the key challenge for complicated techniques and preparation, there were few reports about ternary systems. A series of polyimide/SiO_2-TiO_2 hybrid films with different contents of inorganic particle were fabricated using tetraethoxyl silicane and tetrabutyl titanate as precursor in situ with sol-gel method and both phases in situ. Chemical structure and micro-morphology of hybrid films were studied by means of IR, SEM and XRD.

From the fields of regional crust-mantle structure, metallogentic settings, history of tectonic-magmatic activity, distribution of high antimony anomaly, characteristics of deposit, origin of ore-forming materials (including Sb, C, Si, S, solution and associated elements), black dikes, the relation of deposit and mantle metasomatism fluid is expounded by means of geology and geophysics. Xikuangshan antimony deposit is proved to be a typical vein deposit formed by mantle metasomatism fluid. On the basis of this knowledge, the prospecting criteria of blind orebody of the deposit are given as follows: extensive structuer which indicating the activities of mantle metasomatism fluid, change of host rocks (especially exsisting shale barrier bed), silication and carbonization alteration.

The UMG polysilicon can be produced by heating the purified (NH4)2SiF6 above 500℃ in H2/Ar atmosphere. FTIR and XRD results show that amorphous polysilicon granules can be prepared after heat-treatment of (NH4)2SiF6 in a reducing atmosphere. The reduction of silicofluoride salts is a viable method for the production of UMG-Si.
