Any ceramic material, which is used for its electrical properties is known as electroceramics. These electroceramics are the materials that are used for their distinct storage, magnetic and optical properties. The different forms of electroceramics are fast ion conductor ceramics, magnetic ceramics, dielectric ceramics, electronically conductive ceramics and piezoelectric and ferroelectric ceramics. This book unfolds the innovative aspects of electroceramics, which will be crucial for the holistic understanding of the subject matter. As this field is emerging at a rapid pace, the contents of this textbook will help the readers understand the modern concepts and applications of the field.
