摘要	Ag-coated alpha-Al(2)O(3) powders were synthesized using silver electroless deposition process, which was carried out in an ammonia-based coating solution containing silver nitrate as a starting material. In the case of using pretreated alpha-Al(2)O(3) powders, a thin layer of Ag was coated on the alpha-Al(2)O(3) powders providing a core-shell structure. The thin layer of Ag in thickness had an amorphous structure of about 5 nm. Some crystalline Ag particles about 10 nm in diameter were also observed. However, in the case of using alpha-Al(2)O(3) powders that were not pretreated, large Ag particles about 100 nm were formed, although a core-shell structure was found on the surface of alpha-Al(2)O(3) powders.
