SiO2 gels containing dispersed fine Te metal particles have been prepared by the sol-gel method using a starting solution containing Tetraethoxy Silane (Si(OC2H5)4), H2O, Ethylalchol (C2H5OH), Nitric Acid (HNO3) and Tellurium Tetracholoride (TeCl4) in a several molar ratio. Gelling time of sols was about 3 days and viscosity of solution was very low about 2~3 cP for 3 days. Heat-treatments of the gel have been performed at 500, 700, 900, 1100 and 1300 C for 1 hour, respectively. We have investigated TG-DTA, X-ray diffraction patterns and SEM of heat-treatmented gels. The size of Te fine particles dispersed in SiO2 gel was about 0.8~1 μm and the shape was almost quadrangle.
