Electric Arc Synthesis of Titanium Carbide Using Carbon Obtained by the Thermal Conversion of Food Industry Wastes.

The results of obtaining titanium carbide by a vacuum-free electric arc method using various types of biocarbon obtained by classical pyrolysis of biomass waste, such as tangerine peel, pomelo peel, banana peel, pine nut shells, and walnut shells, are presented. An analysis of X-ray diffraction patterns of the synthesized materials showed the repeatability of the experiment with the receipt of diffraction maximums indicating the formation of a cubic structure of titanium carbide. An analysis of the thermal oxidation of the resulting powders showed that the process proceeded slowly up to 1000°C, but the rate of oxidation increased significantly with temperature. It has been established that the weight of the studied titanium carbide powders obtained using various types of carbon increased upon thermal heating in an oxidizing atmosphere, as confirmed by thermogravimetric analysis.
