Abstract

Copper coating on graphite powders was carried out by cementation process from copper sulfate solution. Effects of operation variables such as copper ion concentration, stirring speed, reaction time and temperature were investigated to obtain optimum conditions for continuous and uniform copper coating on graphite powders. The activation energy of the copper coating process was found to be 3. 59kcal/mole.

황산동 수용액으로부터 치환법을 이용하여 흑연입자에 동을 코팅시켰다. 흑연입자표면에 연속적이고 균질하게 동이 코팅된 최적조건을 확립하기 위하여 동이온 농도, 교반속도, 반응시간 및 반응온도 등의 영향을 조사하였다. 이때 동 코팅반응의 활성화에너지는 3.59kcal/mole이었다.
