چکیده انگلیسی
Ultrafine nickel powders have been prepared by polyol method using NaOH, Ni(NO3)2·6H2O, ethylene glycol (EG) and polyvinylpyrrolidone (PVP) as raw materials at different conditions. Effects of water content of Ni(OH)2 and concentration of NaOH on preparation nickel powders were studied. X-ray diffraction (XRD) patterns showed that the nickel powders were not only face-centered cubic crystallite, but also hexagonal crystallite when the concentration of NaOH increased. In addition, the oxidation products were studied and CO32â of the products was identified through IR spectrum.
