Abstracts
Ultrafine 90% TaC-10% Co powder was fabricated by carbothermal reaction using TaCl4 salt as raw material.
The mixed solution of TaCl4 and aqueous Co nitrate was spray dried and calcined at 700�C. The calcined tantalum
based oxide was composed of an agglomerate of ultrafine particles. The mixed powder of tantalum based oxide and
carbon was heat-treated at 1,100~1,350�C. The formation of ultrafine TaC powder could be achieved by heat
treatment at 1,250�C for 2 hours.
