Ceramic

Burnt clayware, consisting of a mixture of sand and clay, shaped, dried and finally fired in a kiln. Main types include terra-cotta, used mainly for unglazed air bricks, chimney pots and floor tiles; fire clay, used for flue linings since it has a fire resistance; vitreous china, used for plumbing fixtures and sanitary appliances.

ceramic

[sə′ram·ik]
(materials)
Inorganic, nonmetallic materials processed or used at high temperature, generally including oxides, nitrides, borides, carbides, silicides, and sulfides. Intermetallic compounds such as aluminides and beryllides are also considered ceramics, as are phosphides, antimonides, and arsenides.
Consisting of such a product.

ceramic

Any of a class of products, made of clay or a similar material, which are subjected to a high temperature during manufacture or use, as porcelain, stoneware, or terra-cotta; typically a ceramic is a metallic oxide, boride, carbide, or nitride, or a mixture or compound of such materials; hard, brittle, and an electrical insulator.

In addition to the "stock" Eatonite valve seat (the conventional material used in production engines), SwRI tested two advanced ceramic compounds: silicon-aluminum-oxygen-nitrogen (SiA1ON) and sintered-reaction-bonded silicon nitride (SRBSN).
In the case of high-temperature superconductors, the missing factor-the elusive culprit-is the mechanism that allows certain copper oxide ceramic compounds to conduct electricity without resistance.
The list includes knives and scissors that never need sharpening, automobile engines of silicon nitride that weigh 40 percent less and have better heat resistance than current motors, noncorrosive bioceramic implants to replace joints in the aged, superconductors made from esoteric ceramic compounds, and ceramic hammers that can chip concrete.

Since the 1987 announcement of ceramic compounds that superconduct at liquid-nitrogen temperatures, visions of cheaper, cleaner energy production, magnetically levitated trains and exotic technologies have filled scientists' imaginations.
