Abstract
The results of investigation of thermal resistance on air of Me-C nanocomposites containing Fe, Ni and Fe-Ni mixtures have been given in the present paper. Thermal analysis of samples produced by arc-discharge method due to the evaporation of pure graphite and its mechanical mixtures with ferromagnetics (Fe, Ni, Fe-Ni) have been performed using the derivatograph Q-1500D in conditions of dynamic heating from room temperature to 1,000°C. The results of mass change (TG), the rate of mass change (DTG), heat changes (enthalpy change, DTA) for synthesis products during the heating process have been obtained. The results of thermal investigation of products produced by joint evaporation of graphite and ferromagnets, the X-ray phase analysis for graphite samples with ferromagnets before and after oxidation and the temperature dependence of TG, DTG, DTA curves for samples produced by evaporation of pure graphite and mechanical mixtures (C + Fe; C + Ni; C + Fe + Ni) have been presented. On the basis of the performance of experiments it is necessary to notice that smooth mass decreasing of soot in the low temperature range occurs due to amorphous carbon burning. Under heating till 600°C fullerene-liked nanostructures oxidation occurs, and during the following temperature growth the oxidation of graphitized mass proceeds and possible multi-wall carbon nanotubes begins. The investigations have shown that produced Me-C nanocomposites are oxidized in higher temperature range than the pure soot. Increasing of upper interval of temperature oxidation may be explained by ferromagnetics (catalysts of nanotubes growth) and multywall nanotubes oxidation. Decreasing of the temperature of oxidation beginning can be explained by formation of amorphous soot-liked phase in the samples.
