Paper Title:
Study on in-Situ Preparation and Growth Mechanism of TiCxN1-x Whiskers
  Abstract

TiCxN1-x whiskers were prepared using TiO2 and carbon mixed powder as the starting powder at the atmosphere of nitrogen by the carbothermal reduction process. NaCl and NiCl2 were added into the starting powder as the cosolvent and growth adds of impurities, respectively. An effect of the content of TiO2 and carbon in the starting powder on the TiCxN1-x whiskers was investigated. It is found from SEM and XRD observations that three types of TiCx N1-x whiskers are obtained when the different mol ratios of C and Ti are applied. The growth of whiskers is not only urged by the droplet on the top of whiskers, but also initiated by the helical dislocations. The growth of TiCxN1-x whiskers is controlled by the vapor-liquid-solid mechanism as well as vapor-solid mechanism.
