摘要

Magnetic ferrocarbon materials based on a nanocomposite of natural polysaccharide arabinogalactan with magnetite nanoparticles were obtained by heat treatment. In the process of thermal destruction with heating to 410–430 °C in an oxidizing atmosphere, nanosized carbon-shielded magnetite particles are formed. The obtained ferrocarbon powders are finely dispersed showing an average predominant nanoparticle diameter of 5–6 nm. The study of the analysis of ferrocarbon material formation was conducted using electron paramagnetic resonance and synchronous thermal analysis methods. Morphometric parameters were studied by transmission and scanning electron microscopy, as well as laser confocal microscopy. Structural changes were analyzed by X-ray diffraction analysis, magnetic resonance and infrared spectroscopy, which confirmed the preservation of the magnetic phase of magnetite during the carbonization of the organic matrix.
