摘要
The present invention comprises the steps of (I) mixing silicon powder, carbon black powder and vanadium metal powder, followed by primary heat treatment at 1,350 to 1,800°C; (II) after the first heat treatment, a second heat treatment at 1,800 ~ 2,000 ℃; And (III) after the second heat treatment, performing a decarburization process at 600 ~ 1,000 ℃; provides a method for producing a vanadium-doped silicon carbide powder comprising a. According to the present invention, it is possible to obtain a vanadium-doped silicon carbide powder in which vanadium is uniformly distributed in a silicon carbide lattice by a direct carbonization method, and also by using a vanadium-doped silicon carbide powder obtained according to the production method of the present invention 1 By showing a high resistance value of x 10
