| Summary: | Diamond, emerald, ruby and jade are only a few samples of ceramic gems and jewels. Electronic ceramics have conduction behaviors from insulators, to semiconductors, to metallic conductors, to superconductors, and ionic conductors; and have many other very attractive properties such as opto-electrical property, thermoelectricity, ferroelectricity, piezoelectricity, magnetic property, electrochemistry, etc. They have been widely used as sensors, actuators, transducers, and many electronics devices such as high temperature heating elements, varistors, solid fast-ion conductor battery, fuel-cells, humidity detectors, gas sensors by nano-particles, capacitors, gate dielectrics of SiO2 and high-k optical switch and information storage, microwave filters, etc. Many of these applications are discussed in this paper, with basic principle of all the properties covered, this paper aimed to share the importance and significant roles engineered ceramics play in major technological advancement in the future.
