Abstract
Several pure metal oxide particles, including iron oxide, manganese oxide, copper oxide and nickel oxide, were passed through a reducing plasma. The plasma was formed by injecting reducing gases, such as carbon monoxide or hydrogen, into a carbon arc. After passing through the plasma, the particles were quenched in water. The internal structure and surface morphology of the plasma-treated particles were studied using optical and scanning electron microscopy. The factors controlling plasma arc stability during particulate processing were also examined.
