RationaleKnudsen effusion mass spectrometry (KEMS) has been a powerful tool in physical chemistry since 1954. There are many excellent reviews of the basic principles of KEMS in the literature. In this review, we focus on the current status and potential growth areas for this instrumental technique.MethodsWe discuss (1) instrumentation, (2) measurement techniques, and (3) selected novel applications of the technique. Improved heating methods and temperature measurement allow for better control of the Knudsen cell effusive source. Accurate computer models of the effusive beam and its introduction to the ionizer allow optimization of such parameters as sensitivity and removal of background signals. Computer models of the ionizer allow for optimized sensitivity and resolution. Additionally, data acquisition systems specifically tailored to a KEMS system permit improved quantity and quality of data.ResultsKEMS is traditionally utilized for thermodynamic measurements of pure compounds and solutions. These measurements can now be strengthened using first principles and model‐based computational thermochemistry. First principles can be used to calculate accurate Gibbs energy functions (gefs) for improving third law calculations. Calculated enthalpies of formation and dissociation energies from ab initio methods can be compared to those measured using KEMS. For model‐based thermochemistry, solution parameters can be derived from measured thermochemical data on metallic and nonmetallic solutions. Beyond thermodynamic measurements, KEMS has been used for many specific applications. We select examples for discussion: measurements of phase changes, measurement/control of low‐oxygen potential systems, thermochemistry of ultrahigh‐temperature ceramics, geological applications, nuclear applications, applications to organic and organometallic compounds, and thermochemistry of functional room temperature materials, such as lithium ion batteries.ConclusionsWe present an overview of the current status of KEMS and discuss ideas for improving KEMS instrumentation and measurements. We discuss selected KEMS studies to illustrate future directions of KEMS.

AbstractModern high-temperature technologies and methods of production of advanced materials impose new requirements on the quality of information on physicochemical properties of oxide systems at high temperatures. Normally, thermodynamic approach for these purposes is the most fundamental and essential. Great attention was paid by M.M. Shultz to extensive development of this approach in the studies of oxide melts, crystals, glasses, ceramics, and coatings using calorimetric, EMF, and high temperature mass spectrometric methods. Advantages of the thermodynamic approach were illustrated by examples of application of the Knudsen effusion mass spectrometric method to studies of oxide systems and materials, which were crucial for the further development of space and aviation industry, energetics, instrument making, communication engineering, metallurgy, energy-saving, and environmental safety. In the discussion of the regularities of vaporization processes and changes of thermodynamic properties in oxide systems, a number of particular systems based on silica and hafnia was considered in detail. Modeling was carried out for these systems using the Generalized Lattice Theory of Associated Solutions. The obtained results assert a necessity for creation of the national thermodynamic data- and model bases essential for further prediction of phase equilibria in oxide systems and materials at high temperatures.
