At first a physical description of basic properties and basic types of materials for electrical engineering is carried out. Types of conductors, superconductors, insulators, magnetic materials and semiconductors, which are used in power electrical engineering, are presented. The stress is put on relationships between properties, technology and the use. The student will meet, in higher detail, with ceramics for electrical engineering, with properties of mica, glass and their applications, with environmental conductive joining, with materials for thin and thick films and with selected nanomaterials and their applications.
Active attendance and accomplishment of tasks at tutorials are necessary conditions for award an assessment. A student must get an assessment before an examination. A knowledge of a lectured and tutorial matters will be required at examination.
The aim is to identify the structure and properties of basic materials used in electrical power and to become familiar with the measurement of these properties. Acquired knowledge is essential for the subsequent courses of technological nature.
