무전해 도금법을 이용한 코어 셸 구조의 Cu-Ag분말 제조

다국어 초록 (Multilingual Abstract)

Cu-Ag powder having Core-Shell structure was prepared from by electroless plating method using agents such as AgNO₃, NH₄OH, Hydroquinone. Ag coated copper powders were analyzed using scanning electron microscopy(SEM) and energy dispersive X-ray spectrometer(EDX). The silver coating layer of copper powder was affected from various reaction conditions such as molar ratio of NH₄OH, AgNO₃, and pulp density. Free silver was generated below 0.1M or 0.3M and above of NH₄OH mole ratio. Silver coating layer thickened as addition of AgNO₃. When the pulp density reached 12% with 0.2M NH₄OH, and 0.15M AgNO₃ at 4℃, silver was homogeneously distributed around the copper particles and free silver particles were not generated.
