Zirconia gels dispersed with fine Au particles have been prepared by the sol-gel method. Starting solution with (OC Zr 4 H 9 ) 4 , C 4 H 9 OH, H 2 O, HNO 3 , HAuC1 4 was used to prepare gels in several molar ratio. After hydrolysis, viscosity of solutions as 4∼5 cP and gelling time of sols were spent about 9 days. As the heat-treatment temperature was increased, ZrO 2 had the phase transition from tetragonal to monoclinic at 750 ? C . Heat-treatments of the gel have performed at 500, 700, 750, 800, 1000 and 1100 ? C for 3 hrs, respectively. We have investigated TG-DTA, X-ray diffraction patterns, SEM and EDS. The size of Au fine particles dispersed in the heat-treatmented gel was about 0.15∼0.23 μm and the shape was most sphericity.
