Abstract
 은 콜로이드 용액을 이용하여 은이 침적된 생체활성 세라믹 복합체를 제조하였다. 제조된 은 콜로이드 용액과 생체활성 세라믹 복합체의 물리적 특성은 각각 X-선 회절분석기, 라만분광기, 전자현미경으로 분석하였다. X-선 회절분석 자료에 의하면 은 나노입자의 표면에 염소이온이 화학적으로 결합 한다는 사실을 알 수 있었다. 또한 전자현미경 분석에서는 은이 침적된 생체활성 세라믹 복합체의 표면에 염화은이 균일하게 분포하는 것을 알 수 있었다. 따라서 생체활성 세라믹 복합체 표면의 염화은이 생체활성 세라믹 복합체의 하이드록시아파타이트 형성을 강하게 방지한다는 사실을 확인할 수 있었다.

Ag-Doped bioactive ceramic composites were prepared by colloidal silver solution. The physical properties of colloidal silver solution and Ag-Doped bioactive ceramic composites were characterized by Scanning electron microscopy(SEM), X-Ray Diffractometer(XRD) and Raman spectrophotometer respectively. According to XRD, we have identified that the chloride ion was chemically attached silver nano particles. SEM studies showed that silver chloride phases were homogeneously distributed on the Ag-Doped bioactive ceramic composites surface. Finally, we concluded that the silver chloride phase on the Ag-Doped bioactive ceramic composites surface was strongly prevent formation of Ag-hydroxyapatite.
