Advanced ceramics definition.

Advanced ceramics association usaca is a 501 c 6 business league that champions the business interests of the advanced ceramic producers and end users. Advanced ceramics represent an advancement over this traditional definition. These terms cover many different and in part highly specialized ceramic materials with unique mechanical electrical thermal and biochemical properties and property combinations. A ceramic material is an inorganic non metallic often crystalline oxide nitride or carbide material.

Advanced ceramics provide the basis for ceramtec products. This chapter defines the term traditional ceramics which has become associated with the extensive group of more commonly known and longer recognized materials and products a clear line between advanced and traditional ceramics cannot possibly be drawn. Some elements such as carbon or silicon may be considered ceramics ceramic materials are brittle hard strong in compression and weak in shearing and tension. Advanced ceramics synonyms advanced ceramics pronunciation advanced ceramics translation english dictionary definition of advanced ceramics.

Through the application of a modern materials science approach new materials or new combinations of existing materials have been designed that exhibit surprising variations on the properties traditionally ascribed to ceramics. Structural ceramics include bricks pipes roofing tiles and floor tiles. Advanced ceramics advanced ceramics chemical bonding.
