摘要：
Crystalline metallic nickel nano-particles were synthesized using combustion route with mixture of glycine and ammonium nitrate. Characterization of the as prepared solids carried out by X-ray diffraction (XRD), transmission electron micrograph (TEM) and vibrating sample magnetometer (VSM) techniques. The XRD results revealed that the metallic nickel nano-particles crystallize in the cubic form using equimolar ratio of glycine and ammonium nitrate. The TEM measurements of the as-synthesized powders showed formation of irregular and homogeneous particles. Using mixture of glycine and ammonium nitrate as fuel for preparation of metallic nickel by combustion method is better than urea which led to formation of nano-crystalline nickel oxide only. The magnetization value of the as prepared Ni measured at room temperature is greater than the value observed for commercial Ni powder.
