This experiment course aims to learn the properties and evaluation techniques of dielectric and electric properties of bulk ceramics. The students are expected also to learn about the relationships of these properties with structure, chemical composition and physical properties. Processing techniques are also included. In the advanced step, the students can make their own experimental plan on the synthesis and evaluation of ceramics materials concerning with the properties learned in the fundamental step.
Learn about the fundamentals on the experiments concerning with dielectric and electric properties of ceramic materials. Planning of the original experiments is for growing the students' potential of planning, practice, presentation etc for materials researcher.
bulk ceramics, ferroelectrics, dielectric constant, electric conductivity

To enhance effective learning, students are encouraged to spend approximately 50 minutes preparing for class and another 50 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.
The text book, "Ceramics experiments 2022" will be provided.
Fundamental lecture course 1: Ceramics experiments; Uchida-rokaku-ho
Other documents will be provided.
Students are requested to join and carry out all the experiments, and do the proposed tasks to judge their knowledge on the experiments and ceramics.
Students are recommended to learn about the fundamental knowlegde on ceramic materials in 1st or 2nd year.
