Preparation and Antibacterial Activity of Al2O3-ZrO2 Carrying Ag+

Abstract:

Article Preview

A group of new composite antibacterial agent was prepared by ion adsorption method, in which silver ion is the main active ingredient, with alumina and zirconia as the carriers. The influence of mixing time, content of zirconia, silver ion content and calcination temperature on the antibacterial properties of the composite powder are discussed in this paper. The results show that when the content of ZrO2 is 4%, Ag+ content is 4%,mixing temperature is 70°C,mixing time is 4h, the composite antibacterial agent has a good property. ZrO2 can be loaded in the large hole of Al2O3 as a second carrier; it can keep a larger surface area-based carrier, suitable pore structure, and also play an important role on antibacterial properties at high temperature.
