Content:

  • Basic systematic crystal chemistry: chemical and topological classification; fundamental structure types.
  • Structure and chemical bonding.
  • Principles of structure-property relations in inorganic solids (mechanical, electrical, magnetic, thermal properties etc.).
  • Structural defects and structural phase transitions and their influence on macroscopic properties.
  • Crystal chemical tailoring of materials properties (doping, substitution etc.).
  • Selected examples of technically important materials (e.g. perovskites, spinells, semiconductors, oxide- and non-oxide ceramics, ultra-hard materials, refractories etc.)

Goals:

Lecture: The students acquire a basic understanding of the building principles of crystal structures in terms of chemical bonding and structural topology. This includes an overview over the most important structure types and of structure-property relations in inorganic (non-metallic) engineering materials.

Exercise: The students will learn “hands-on” how to understand, draw and interpret crystal structures both qualitatively (identify structure type, identify coordination, describe polyhedral linkage etc.) and quantitatively (derive bond-lengths and -angles, discuss bond-strength and derive structure related properties).
