Effusion Method

The Knudsen effusion method has been applied in a study of the vapor pressures of manganese in equilibrium with copper–manganese alloys at high temperatures. The amount of manganese effused was determined by the use of radioactive Mn54. The odd behavior noted in this system at 20–30% Mn, observed in a number of studies of various physical properties, has been observed once more in the apparent activity of manganese. Some discussion is given of the Knudsen effusion method, particularly regarding some possible sources of error.

Vaporization and sublimation enthalpies of six peroxide containing derivatives of carboranes were obtained on the basis of temperature dependencies of the saturated vapor pressure that was measured by Knudsen effusion method. Fusion enthalpies were defined by DSC method. The inputs of carborane nuclei and the increments of the hydrogen atom deputies groups in carboranes were determined.
