Thermodynamische Zustandsgrößen von Alkalimetallplasmen und von deren Komponenten / Thermodynamic Properties of Alkali Metal Plasmas and of their Components

Abstract

Thermodynamic functions of plasmas of alkali metals and of their components - diatomic molecules, atoms, simply charged ions and electrons - are calculated in the temperature range 298.15 °K -10000 °K. At this it is supposed, that the plasma is in thermodynamic and chemical equilibrium and in an ideal gas state. The internal partition functions of the components of the plasmas are calculated by summation term by term up to characteristic quantum numbers. These characteristic quantum numbers are determined by graphic and calculating methods. The thermodynamic functions of alkali metal plasmas and their components are discussed and compared with results calculated by approximative methods.
