Ceramics, glasses and glass-ceramics have been playing an increasingly important role in the development, design and construction of new systems and their components for many years. The reason for this is that this material group has completely different material-specific properties compared to metals and plastics and the associated machining and processing properties. Wherever there are problems with metals or plastics in connection with, for example, heat resistance, chemical or mechanical wear, glass and ceramics can be used. Based on these different properties, it is therefore of fundamental interest to know the structure of all glasses and ceramics and to be able to consider or derive their material suitability as well as their peculiarities, including the resulting processing parameters and limitations of use. The particular importance of the technical properties of this group of materials for the design of components is demonstrated using various practical examples.

3. Glass ceramics
   Glass ceramics and structure
   Raw materials, production and influence on properties
   Types of glass ceramics, properties and their application
4. Technical ceramics
   Ceramics and structure

8. Current developments

The total workload for the module is 150 hours (see also "ECTS credit points and grading").

• Written examination

Examination: see the applicable study regulations

The module assumes basic knowledge of materials engineering, as acquired in introductory modules in materials engineering or chemistry.

Students who would like to refresh their knowledge and skills before starting the module are recommended to read the following basic literature:

Ashby, M. F., & Jones, D. R. (2012). Engineering materials 1: an introduction to properties, applications and design (Vol. 1). Elsevier.

Students can identify different products from the material groups of glasses, glass-ceramics and ceramics and differentiate between them with regard to the expected properties.

Students who have completed this module are able to assess glasses, glass-ceramics and ceramic materials with regard to their suitability for use in components. They are also able to outline various manufacturing processes.

Students understand material relationships, can select the appropriate material according to a requirement profile and are able to design material-appropriate constructions for glasses, glass ceramics and ceramics.

Students who have passed this course will be able to characterise and categorise ceramic and glass-ceramic materials and glasses, test, present and evaluate mechanical, thermal and chemical properties. Students will be able to establish and interpret microstructure-property correlations of the material groups and present and justify the application of the materials in technology.

Students are familiar with the specific technical terminology and can use the terminology correctly. They differentiate between the material groups glasses, glass-ceramics and ceramics and take into account the specific material properties in group work/discussions.
