Supervisor: prof. Ing. Martin Trunec, Dr.  
Supervising institute: ÚMVI all courses guaranted by this institute
Teaching language: Czech
Aims of the course unit:
The course will provide students with the advanced physico-chemical knowledge required for experimental study in the field of structure and properties of ceramic materials and composites.
Learning outcomes and competences:
Graduate of the course will be able to apply the acquired knowledge in doctoral study of material engineering and in particular in solving dissertation work connected with research in the field of advanced structural, electroceramic and bioceramic materials.
Prerequisites:
Knowledge of material sciences and engineering at Masters level.
Course contents:
The advanced course of non-metallic inorganic materials focused on the structure of ceramic materials and their physical and chemical properties. The topics of the course: diffusion in ceramic materials, mechanical behavior of ceramics, high temperature engineering ceramics, ceramic superionic conductors, ferroelectric ceramics, ferrimagnetic ceramics, semiconducting, polycrystalline ceramics, oxide superconductors, biomaterials for surgical usage.
Teaching methods and criteria:
The course is taught in the form of lectures and consultations, which have the character of explanation of basic principles and theory of the given discipline.
Assesment methods and criteria linked to learning outcomes:
The examination of the theoretical knowledge assessment and its practical application will take the form of a 30-minute presentation with a discussion on advaced ceramic topics close to the doctoral dissertation's goals.
Controlled participation in lessons:
Depending on the number of participants, the course will take the form of consultations or lectures. At the end of the course the doctoral student will prepare a thematic presentation in the field of advanced ceramic materials.
Type of course unit:
    Lecture  10 × 2 hrs. optionally
