Abstract

The paper describes the most significant methodological approaches to determining the thermodynamic properties of inorganic systems by high-temperature mass spectrometry; the approaches have been first proposed by L.N. Sidorov and are being commonly used in domestic laboratories. In this context, the complete isothermal vaporization and “third component” methods and the generalized equation of the Belton–Fruehan method are discussed; currently, they are essential in modern mass-spectrometry thermodynamic studies of inorganic systems and materials. It is shown that an MI-1201 mass spectrometer adapted for high-temperature studies of neutral molecules and ion–molecule equilibria in vapor over inorganic systems has certain advantages in studying materials.
