Abstract
Results are reported of an experimental study of superheated rubidium vapor in the temperature range 1450–2000 K and pressure range 1.7–5.2 MPa and potassium in the range 1500–2100 K and 1.4–4.0 MPa. The experiments have been performed with an apparatus adaoted to implement a modified constant-volume piezometer technique, where the sensing element of a pressure transducer represented by a diaphragm is placed in a low-temperature zone. A dosing device is described which permits the performance of accurate measurements of the mass of the metal in the piezometer chamber. The present results are in good agreement with those reported by other investigators in the overlaping temperature and pressure ranges.
