Abstract
Dispersed nickel particles on Spherocarb were prepared at 540$^{\circ}C$ in various reaction atmosphere. Magnetic properties of these samples were determined, and results were compared with those of unsupported and MgO supported nickel particles. It was shown that nickel react primarily with carbon regardless of reducing atmosphere. In addition, apparent possibility of nickel-carbon interaction was discussed.
540$^{\circ}C$에서 탄소에 분산된 니켈 입자를 제조하여 니켈 덩어리 및 산화 마그네슘에 지지된 니켈 입자의 자기 특성과 상호 비교 검토하였다. 환원대기에 무관하게 니켈은 탄소와 반응함을 알 수 있었다. 또한 니켈-탄소간의 상호작용 가능성에 관하여 논의하였다.
