Detonation Synthesis of Carbon-encapsulated Alloy Nanocomposite Materials

摘要：

Carbon-encapsulated Ferrite-Nickel and Ferrite-Cobalt alloy powders were prepared by detonation technique in inert atmosphere. These composite nanoparticles were characterized by means of X-ray diffraction (XRD), Transmission electron microscopy (TEM), Energy Dispersive X-ray Detector(EDX), Raman spectrometer (RS) and Vibrating sample magnetometer (VSM) characterization methods. The results showed that well-crystallized alloy nanoparticles existed in the detonation soot and the average grain size was 20～35 nn, the detonation soot consisted of cobalt cores and carbon shells in the form of core-shell structure, the coating layers were mainly consisted of graphite carbon phase. The magnetic hysteresis curves demonstrated that the prepared nanoparticles exhibited superparamagnetism.
