PURPOSE:To efficiently produce TiC whiskers having excellent straight elongation and high aspect ratio by a solid-phase reaction method. CONSTITUTION:In a process of blending a Ti source raw material composed of titanium dioxide or an alkali metal titanate, a carbon material of carbon black, a catalyst of Ni or Co chloride, a powdering inhibitor of sodium chloride to give a raw material system and reacting the raw material system in an inert atmosphere under heating, the temperature condition in the reaction under heating is set at 2-15 deg.C/minute and 1,400-1,700 deg.C heating temperature range. |
