Abstracts
Tungsten carbide powder was fabricated with carbothermal reaction by pulsed electric current flowing in compact
of tunsten oxide and carbon. The mixed powder of tunsten oxide and carbon was ball-milled into ultrafine powders.
The mixed powder of tungsten oxide and carbon was put into carbon mold and heat-treated at 1050~1200C by
pulsed electric current flowing. The formation of tungsten carbide powder could be achieved by heat treatment at
1200C for 10 minitues.
