摘要: The vapor pressure of zinc has been measured by the Knudsen effusion method using radioisotopeZn65. Measurements have made from 150° to 350°C, and temperature‐vapor relation over this range was found be log10 P mm=—7198/T+9.664. heat vaporization calculated 31.35 kcal per mole at 0°K. A test Clausing probability factor regarding dependence rate on dimensions orifice.
