Abstract

Aimedatsynthesizingtheencapsulationofnickelnanocrystalwithingraphiticcarbon,effectiveexperimentswerecarriedoutbyadjustingthemoleratioofcarbonsourceandmetalsourcein theseprecursors.Thechemicalcomposition,nanostructuresandmagneticpropertiesofthecomposite particleswereanalyzedbyusingX-raydiffraction(XRD),transmissionelectronmicroscopy(TEM), energydispersiveX-raydetector (EDX)andvibratingsamplemagnetometer (VSM).Theresults showedthatthedifferentsizeandsphericalgraphite-encapsulatednickelnanoparticleswithaperfect core-shellstructurehadbeenpreparedandthatthesemagneticcompositeparticlesmainlydistributed in10-55nm.Themagneticmeasurementsdemonstratedthattheas-preparedCENNPstookonsuperparamagneticorferromagneticbehaviorsatroomtemperature.
