Термодинамический анализ гетерогенных химических реакций в системе "Смесь порошков FE – TI – углеводородная жидкость" под воздействием высоковольтных электрических разрядов

Abstract

Thermodynamical analysis of chemical equilibrium for Ferrum and Titanium powders mixture in hydrocarbon liquid medium under the impact of high voltage electric discharges is given. Possibility for obtainment of carbides and intermetallic compounds from components of initial mixture in different phase state is theoretically justified. It is found out that synthesis of Fe₂Ti and TiC is thermodynamically possible at temperatures higher than 300 K and synthesis of Fe₃C and FeTi is possible at temperatures higher than 1100 K. Obtained theoretical results are experimentally confirmed by synthesis of TiC, Fe₃C and Fe₂Ti in Fe – Ti powder mixture after high voltage electric discharge treatment in kerosene.
