The hydroxyapatite(HAp) as a carrier the for ion exchange agent of Ag^+ions was prepared in semiconductor fabrication, The Ca/P molar ratio of the HAp was 1.65. The HAp is molded in shape of the antimcrobial ball and then sintered at 1000℃. Ag-containing HAp(HAp-Ag) was prepared by incorporating Ag＾+ions in HAp crystals through an ion-exchange reaction in solutions containing 0.01M AgNO<sub>3</sub>. The antimicrobial effect of HAp-Ag for bacteria such as Escherichia coli and Staphylococcus aureus has been investigated. The concentrations of silver in the antimicrobial ball was determined by inductively coupled plasma and the amount of Ag^+ion was 9.0㎍/g. The HAp-Ag exhibited excellent antimicrobial effect for bacteria such as E. coli and S. aureus. The bactericidal activity was considered to be caused by direct contact of bacteria with Ag^+ions in the HAp crystals. The HAp would likely to be possible as a carrier of antimicrobial metal ions such as Ag, Cu, and Zn by recycling of waste sludge in the semiconductor fabrication process.
