“…Three different methods of determination of pressure calibration factor are generally applied [11]. The mostly used technique bases on the mass spectrum measurement of the substance with the well-known partial pressure (usually pure metals: Ag, Au, Ni, Pt) at the possibly well defined temperature T (preferentially melting temperature).…”

Investigations carried out by Knudsen effusion mass spectrometry on metals, alloys, oxides, and fullerene systems in the period 1990-2010 are reviewed in the present paper. 362 original papers were published in this period by ca. 45 research groups thereby showing still large activity in this unique area. The fundamentals and recent developments of the method are briefly reported. Data to the systems studied, temperature ranges, vapour species identified in the equilibrium vapours and thermodynamic properties obtained in the study are reported. Important features of these studies are briefly discussed as well.Most of the vaporization studies by Knudsen effusion mass spectrometry carried out on alloys, oxides and fullerenes aimed at the determination of thermodynamic data of gaseous species and condensed phases. Many of the studied materials are of practical importance for modern technologies. The investigations should give information on thermal stability, volatility under different conditions (temperature, oxygen partial pressure, and gaseous impurities), oxidation resistance, reactivity etc.

A Knudsen cell mass spectrometric technique was used to study both the neutral and charged species that are in equilibrium in saturated vapor over lutetium trichloride. It was found that in the temperature range between 885 and 1100 K the vapor is comprised of molecular (LuCl 3 ) n and ionic Cl -(LuCl 3 ) n clusters where n = 1 -6. For neutral constituents, monomer and dimer molecules are the most abundant, the partial pressure of Lu 2 Cl 6 being about 22 per cent with regard to the total pressure at 1000 K. According to thermodynamic calculations dimer molecules become the dominant species of the equilibrium vapor above 1200 K. In the temperature range studied, the temperature dependencies of partial vapor pressures (atm) of monomer, dimer, trimer and tetramer molecules are approximated by the following equations The electron affinity of LuCl 4 superchloride molecule has been estimated to be 3.7 ± 1 eV.
