The Dissociation Pressure of VC at High Temperature and the Thermodynamic Properties

Shiro Fujishiro*

The dissociation pressure of gaseous vanadium in the reaction VC(s)=V(g)+C(graphite) has been determined in the range of 2346∼2545°K by means of Knudsen cell effusion method.
The pressure at the above temperature range is adequately expressed by log Pv(atm)=-30,400/T+7.50, from which, and coupling with the reported heat capacity data, the pertinent thermodynamic properties are calculated.
