Novel synthesis of substoichiometric ultrafine titanium carbide

摘要

Ultrafine titanium carbide particles were synthesized by liquid-magnesium reduction of vaporized TiCl_4 + CCl_4 solution. Fine TiC particles were produced by the reaction of released Ti and C atoms, and after reduction process vacuum was used to remove the residual phases of MgCl_2 and excess Mg. Fixed and free carbon were measured in products synthesized with various parameters as well as stoichiometry and microstructure.
