|Accepted examination and exercises.|
The first part of this course is concentrating to functional ceramics and the second part is concentrating to engineering ceramics. The course gives the students an introduction to functional ceramic materials and relate physical and chemical properties to the structure and composition. The focus is on the thermal, electric, magnetic, and optical properties. After the course the student is able to identify such dependence and has basic knowledge to tailor these properties. Student has also a general picture of their applications in machines, electronics (conductors, insulators, dielectrics, magnets), sensors, energy conversions. The student will be able to identify the most common engineering ceramics and define their main properties with a special emphasis in mechanical properties which are important in engineering applications. The student will be able to name the different testing methods and interpret the results. The students will be able to summarize the main properties, major applications and the limitations of the most common engineering ceramics. The students will be able to define the basic designing methods and apply those for different components. The student will be able to select materials for different applications, especially for applications facing corrosion and wear. The student will be able to name some new trends in engineering ceramics e.g. ceramic composites.
