Return to Vienna for the summer semester of 2022. We are planning to hold courses mainly on site to enable the personal exchange between you, your teachers and fellow students. We have labelled digital and mixed courses in u:find accordingly.

Due to COVID-19, there might be changes at short notice (e.g. individual classes in a digital format). Obtain information about the current status on u:find and check your e-mails regularly.

Information

Aims, contents and method of the course

The lecture gives an overview about different methods used for the characterization of inorganic materials; in particular methods for phase diagram analysis. In the first section we discuss different types of phase diagrams and the possibilities to construct 2-dimensional diagrams of multi-component systems. the preparation of equilibrated samples is discussed. In the second section different methods for the investigation of isothermal equilibria are introduced: metallographic analysis by light optical microscopy, X-ray powder diffraction, scanning electron microscopy and EPMA (Electron Probe Microanalysis). The classical methods of thermal analysis, DTA (Differential Thermal Analysis), DSC (Differential Scanning Calorimetry) and TGA (Thermo Gravimetric Analysis) which are used for the investigation of thermal reactions are the topic of the third section. Finally we will give some practical examples on data analysis and the evaluation of complex phase diagrams based on experimental data.
The theoretical background of the most important methods for phase diagram analysis is discussed, and an overview about experimental techniques, application and data interpretation is given.
