electroceramics

Piezoelectricity is one of the key properties of electroceramics.

Details are given of research projects (engineering ceramics, electroceramics, traditional ceramics).

Historically, developments in the various subclasses of electroceramics have paralleled the growth of new technologies.

It is a component of some "high temperature" YBCOsuperconductors, and electroceramics.

This high ionic conductivity (and a low electronic conductivity) makes it one of the most useful electroceramics.

It has a low sodium content which makes it suitable for the preparation of electroceramics like dielectric materials and piezoelectric ceramics.

Such materials are now classified under electroceramics, as distinguished from other functional ceramics such as advanced structural ceramics.

Other reference books and selected articles on specific topics (e.g. electroceramics, electronic polymers etc.) will be put in reserve at Thode Library during the term.

Piezoelectric transformers made of PZT electroceramics generate high voltage, by electro-mechanical energy conversion based on the piezoelectric effect.

Material classes investigated include nanostructured electroceramics, complex metallic alloys, semiconductor materials and oxide superconductors together with lattice defects by advanced techniques electron microscopy.

Particular areas of interest include disordered systems such as sol-gels and glasses, electroceramics, the sites responsible for catalytic action in zeolites, biomolecules, and the study of high-temperature superconductors.

Colloidal Processing of PZT - Presented at Electroceramics V, University of Aveiro, Portugal, September 1996.

The site covers general information about electroceramics (dielectric materials, electro-optic and electro-chromic materials, semiconductors, ionic conductors and mixed conductors, magnetic materials and superconductors) and their applications.

Research groups cover ceramics (ceramic processing and structural ceramics, photonic materials, electroceramics, carbon materials) and metallurgy (ferrous metallurgy and fabrication, non-ferrous metallurgy and intermetallics).

Also called PZT, it is a ceramic perovskite material that shows a marked piezoelectric effect, meaning that the compound is used in a number of practical applications in the area of electroceramics.

As a nano fabrication technology, the pulsed laser deposition process has the capability of producing unique surface coatings that are not available today for use as superconductors, electroceramics, tribological coatings and metallic alloys.

It is a component of YBCO (high-temperature superconductors) and electroceramics, and is added to steel and cast iron to reduce the size of carbon grains within the microstructure of the metal.
