  • Carbon encapsulated cobalt and nickel magnetic nanoparticles have been synthesized successfully via detonation technique under nitrogen gas in explosion vessel. The gelatine dynamics are mainly made up of RDX explosive, mixed with nitrate cobalt or nitrate nickel, some orgnatic carbon materials at a proportion. Some testing methods such as XRD, TEM, VSM were carried out on the detonation soot, so as to characterize their morphology and properties. The results of experiments showed that the detonation products consisted of carbon encapsulated cobalt and nickel nanomaterials, with the perfect core shell structure. The size of carbon encapsulated cobalt particles distributed between 30 and 50 nm, and the grain of carbon encapsulated nickel nanoparticles was 25~60 nm. At room temperature, they exhibited good soft magnetism.
