Course description and aims

Various phenomena shown in ceramic materials are based on the defect formation and their diffusion. In this course, the basic knowledge of the kinds of defects, the defect formation and diffusion of matter through defects are provided. As an application of the defect and the diffusion, the solid state reaction and the sintering have to be understood through kinetics point of view.

Student learning outcomes

At the end of this course, students will be able to:
1) Have the overview and systematic understanding of the kinetics of the solid state reaction.
2) Have the basic understandings of the defect formation and the diffusion.
3) Understand the solid state reaction and the sintering via the kinetics point of view.

Keywords

Defect, Diffusion, Fick's law, Electrical properties, Solid state reaction, Sintering, Driving force of sintering
