Not applicable.

Students will be able to use the acquired knowledge in the related master studies of material engineering and apply it to the solution of appropriate problems of industrial practice particularly the problems connected with the selection of special structural materials.

Knowledge of physics, chemical thermodynamics and kinetics and also synthesis of ceramics on the level of introductory university courses is assumed.

Not applicable.

The course is taught through lectures explaining the basic principles and theory of the discipline. Teaching is suplemented by practical laboratory work.

Course-unit credit requirements: attendance at seminars and fulfilment of assignments. Examination verifies the knowledge of the theory and its applications to solving practical problems. The exam consists of written and oral parts; students take the oral exam even though they do not succeed in the written part.

Lecture 13 x 3 hrs.
labs and studios 13 x 1 hrs.
