本研究以田口法進行實驗設計並針對不同纖維素種類(因子A)、纖維素添加量(因子B)、反應器轉速(因子C)與還原劑添加量(因子D)等參數，於微細銅粉於化學合成中，針對銅粉之粒徑大小、微結構、重新分散性、沉降速度、晶相所產生之影響進行探討，經實驗後發現各實驗組別皆可合成出晶相均一之銅粉，而纖維素於本研究之反應體系中，除了提供一空間位阻效應防止銅粉顆粒聚集外，也同時提供了一生長界面，提供生成不同形狀之微細銅粉。

In this research， L9 orthogonal array using the Taguchi method and the subjective quantification method were used for u1trafine copper powder analysis. Cellulous types， cellulous-adding weights， stirring rates， and reducing-agent weights were chosen as primarγfactors Particle siz巴， mlcrostructu時， re-dispersion properti肘， settling velocity， and crystal analysis were chosen as desired targets. The experimental results showed that each experiment of L9 can form pure copper powder. Threedifferent cellu10ses not only caused the steric stabilization， but also provided an interface to change the nucleation system. Finally， different forms of u1trafine copper powder with good dispersivity were synthesized during our investigation.
