Pressure dependence of the melting temperature of tungsten carbide up to 80 kbar
Vereshchagin L.F. , Fateeva N.S., Magnitskaya M.V.
The pressure dependence of the melting point of tungsten carbide (WC) was investigated up to 80 kbar in the high-pressure chamber described by us earlier. C1] The investigated samples was placed in these experiment inside the working part of the chamber, which was equipped with lateral viewing windows. The pressure was produced in the chamber by pistons moving towards each other. The pressure generator was a 300-ton hydraulic press. The pressure-transmitting medium, in which the sample was directly place, was rock salt. The stepped windows in the chamber wall were filled with rock salt. The pressure calibration of the setup was based on polymorphic transitions in bismuth, thallium, and barium in accord with the 1968 scale.C2]
