신 열환원 공정에 의한 초미립 티타늄 카바이드 분말 합성

Abstract

Ultra fine titanium carbide particles were synthesized by novel metallic thermo-reduction process. The vaporized TiCl4+CCl4 gases were reacted with liquid magnesium and the fine titanium carbide particles were then produced by combining the released titanium and carbon atoms. The vacuum treatment was followed to remove the residual phases of MgCl2 and excess Mg. The stoichiometry, microstructure, fixed and carbon contents and lattice parameter were investigated in titanium carbide powders produced in various reaction parameters.
