Nonmetallic Materials

FSI-WNEAcad. year: 2019/2020

The introductory course of non-metallic inorganic materials focused on the structure of ceramic materials and their physical and chemical properties. Lectures also provide, in addition to specific information on ceramic materials, the theoretical foundations of chemical thermodynamics and introduction to polymers.

Learning outcomes of the course unit

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 ceramic materials.

Prerequisites

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

Co-requisites

Not applicable.

Planned learning activities and teaching methods

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

Assesment methods and criteria linked to learning outcomes

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.
