摘要：

A new self-induced and efficient route to carbon-encapsulated iron nanocrystallites (ca. 30-60 nm in diameter) using the thermolysis of sodium azide-chlorocarbon mixtures in the presence of ferrocene is presented. The product was purified and its composition and morphology were studied by means of HR SEM, HR TEM, XRD, and DTA/TG. The magnetic properties (the coercivities ca. 60-70 Oe and the saturation magnetization ca. 21-22 emu/g) of encapsulates were measured. This autothermal process has inherent advantages, including the use of low cost materials and the simplicity of the production protocol, and can be also used to obtain other nanoencapsulates.
