Advanced Ceramics Definition

These terms cover many different and in part highly specialized ceramic materials with unique mechanical electrical thermal and biochemical properties and property combinations.

Advanced ceramics definition.

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. This class includes bearings special tiles e g. Reaction sintering or reaction bonding is an important means of producing dense covalent ceramics.

Advanced ceramics association usaca is a 501 c 6 business league that champions the business interests of the advanced ceramic producers and end users. Hesse in concise encyclopedia of advanced ceramic materials 1991. 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.

This material is also referred to as technical ceramics engineering ceramics or industrial ceramics. Advanced ceramics represent an advancement over this traditional definition. Technical ceramics are also know as special fine advanced or engineered ceramics. Advanced ceramics bear little resemblance to their origins.

They withstand chemical erosion that occurs in other materials subjected to acidic or caustic environments.
