Antibacterial materials have been studying in many researches. In this study, sol-gel method was applied to synthesis of antibacterial materials from initial components Ag, TiO2 and ZnO. Ethylenediaminetetraacetic acid (EDTA) was used to produce the medium complexion compounds. Ag/ZnTiO3 powder was formed when the ratio of Ag/EDTA/(ZnO,TiO2) is 0.1:2:1 while Ag/Zn2TiO4 powder was formed when this ratio is 0.1:6:1. The X-ray Diffraction (XRD) results were obtained from these compounds. Then both compounds were tested the antibacterial property with Staphylococcus aureus (S.aureus) in the concentrations of 20mg/ml in 1– 4 hrs.
