Course Objective

Objectives of this course are to make the students understand ceramic conductors, dielectrics, insulators, pieozoelectric pyroelectric, electrooptic and magnetic ceramic materials. Have a first hand experience about the topics of these systems through semester projects.

Learning Outcomes of the Course Unit

1   To understand the components, fabrication and design of ceramic conducting materials,
2   To learn as an interdisiplinary topic since optimum physical and chemical properties of electronic ceramics are described by specific requirements of final usage
3   To interpret the basic science of the origines of a wide range of physical properties including conductive and semiconductive
4   To interpret the basic science of the origines of a wide range of physical properties including dielectric, magnetic, optic, and piezoelectric materials
5   To learn parameters regarding as electronic materials
