Thie experiment course aims to learn the porperties and evaluation techniques of dielectric and electric properties of bulk ceramics. The students is expected also to learn about the relationships of these properties with structure, chemical composition and physical properties. Processing techniques are also included. In the advenced step, the students can make their own experimental plan on the systhesis and evaluation of ceramics materials concering 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
