摘要

Tantalum carbide (TaC_x) whiskers were successfully synthesized via material systems of Ta₂O₅-NaCl-C-Ni, Ta₂O₅-NaF-C-C₁₂H₂₂O₁₁ (sucrose) and Ta₂O₅-KCl-C-Ni systems. It was found that whiskers prepared via different material systems have different morphologies. The lattice parameter and x (C/Ta ratio) increase with the rise of the reaction temperature. All material systems were proceeded under the condition of about 0.1 MPa argon atmosphere and reaction temperatures ranging from 1150 to 1350 °C. The composition, morphology, crystal structure and the growth mechanism were investigated.
