Abstract
The effect of hydrostatic pressures up to 8 kbar on the electrical resistance quenched in platinum has been studied. The formation volume of vacancies was obtained under experimental conditions that minimized necessary corrections due to vacancy interactions and vacancy losses during the quench, as well as various uncertainties in the quench temperature. In particular, special care was taken to monitor the quench temperature accurately by using a specific calibration for the variation of resistance against pressure. The fractional measured value of at 800 °C is 0.67 ± 0.03 atomic volume. Previously published results are reviewed and reanalyzed with the help of the new calibration data.
