Definition Of Ceramics Materials

They are formed by the action of heat and subsequent cooling.

Definition of ceramics materials.

Ceramic materials can be identified by their general properties like high hardness brittleness chemical stability and low thermal conductivity. Advanced ceramics and traditional ceramics are the main categories of ceramic materials. The resulting material may be crystalline semi crystalline or vitreous. 1 clay was one of the earliest materials used to produce ceramics but many different ceramic materials are now used in domestic industrial and building products.

Ceramic materials are inorganic non metallic materials made from compounds of a metal and a non metal. A ceramic material is an inorganic non metallic often crystalline oxide nitride or carbide material. Ceramic comes from the greek word meaning pottery. These material properties are utilized to produce number of commercial and domestic products such as pottery bricks advanced functional items etc.

Nowadays the term ceramic has a more expansive meaning and includes materials like glass advanced ceramics and some cement systems as well. Ceramic materials may be crystalline or partly crystalline. Ceramics may be glazed prior to firing to produce a coating that reduces porosity and has a smooth often colored surface. Many ceramics contain a mixture of ionic and covalent bonds between atoms.

The clay based domestic wares art objects and building products are familiar to us all but pottery is just one part of the ceramic world. Amorphous materials with similar composition are generally termed glass.
