Technology of Electrical Materials

Data is displayed for academic year: 2023./2024.

Course Description

The content of this course are basic engineering knowledges of materials that are embedded in electrical, electronic and communication products and in computer devices. The basic structures and internal connections of conductive, insulating and magnetic materials are described within the course. The emphasis is on the basic physical, electrical, magnetic, technological, thermal and chemical properties of the material. The causes of the ultimate current, voltage and mechanical load of the material are explained. Typical representatives of materials for manufacturing conductive, insulating and magnetic parts of electrical products are introduced. The content of the subject are also the basic characteristics of semiconductors, composites and nano-materials. The mechanisms of the effect of techno-climatic conditions on the durability and reliability of electrical products are explained. They learn basic procedures for selecting and testing materials, and disposing of discarded products and protecting the environment.
