Abstract
The effect of high energy ball milling on the NiO reduction by zinc powder has been studied. XRD analysis on the as-milled mixtures of NiO-Zn with stoichiometric composition indicated that the traces of nickel phase observed after 30 min milling and the NiO reduction reaction by Zn progressed gradually during milling procedure. DTA analysis on the raw mixture (un-milled sample) with stoichiometric ratio under high pure argon atmosphere showed that the reduction of NiO by Zn occurred at about 630 °C. The final products in both as-milled and isothermally heated of un-milled samples were mainly the mixtures of ZnO and Ni0.6Zn0.4O phases.
