Abstract

Ni nanopowder was synthesized from NiO through mechanically induced magnesiothermic NiO–Mg reaction that can also be regarded as a kind of progressive synthesis, or Mechanically induced Self-sustaining Reaction (MSR). The obtained powder was characterized by XRD, FESEM, and TEM. After 8 min of milling, the mixture ignited in the mill vial to yield Ni and MgO. The latter was removed by leaching with 18% HCl. The mean crystallite size of resultant Ni was found to have a value of 45–50 nm.

NiO-Mg系统中机械合成的镍纳米粒子

摘要

Ni纳米粉是通过机械诱导的镁热NiO-Mg反应由NiO合成的,也可被视为一种渐进合成或机械诱导的自持反应(MSR)。所获得的粉末通过XRD,FESEM和TEM进行表征。研磨8分钟后,混合物在研磨瓶中点燃,产生Ni和MgO。通过用18%HCl浸提除去后者。发现所得镍的平均微晶尺寸为45-50 nm。
