Abstract:

The Bi III-V and IV-V equilibrium boundaries were studied by monitoring electrical resistance changes. Extrapolation of the III-V data to 25C yields an equilibrium transition pressure of 77.5 kbar. The extrapolation also agrees within experimental error with the pressure of 78.2 kbar determined in a separate experiment at 22C. The use of the transition as a calibration point is discussed, and a procedure for estimating the compression-stroke transition pressure from the equilibrium transition pressure is proposed. This involves adding 2 kbar to the equilibrium pressure at room temperature. Author
