Definition Of Ceramics In Material Science

A ceramic is a material that is neither metallic nor organic.

Definition of ceramics in material science.

Materials science and engineering. The properties of ceramics however also depend on their microstructure. Nowadays the term ceramic has a more expansive meaning and includes materials like glass advanced ceramics and some cement systems as well. Ceramic encompass such a vast array of materials that a concise definition is almost impossible.

Solid pure silicon and carbon may be considered to be ceramics. Advanced ceramics and traditional ceramics are the main categories of ceramic materials. In the past glass was considered a ceramic because it s an inorganic solid that is fired and treated much like ceramic. Ceramics are hard and strong but brittle.

A ceramic material is an inorganic non metallic often crystalline oxide nitride or carbide material. However one workable definition of ceramics can be expressed as follows. Ceramics are typically hard and chemically non reactive and can be formed or densified with heat. Different materials have different properties.

The ordered internal structure of ceramics plays a large role in their properties. These material properties are utilized to produce number of commercial and domestic products such as pottery bricks advanced functional items etc. For example one type of ceramic cordierite a magnesium aluminosilicate is used as a substrate and support for catalysts in catalytic converters. 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.

Science and technology 2001. A ceramic is a refractory high temperature heat resistant inorganic and nonmetallic material. They withstand chemical erosion that occurs in other materials subjected to acidic or caustic environments. Arnold in encyclopedia of materials.

Sometimes even monocrystalline materials such as diamond and sapphire are erroneously included under the term ceramics. It was chosen for this purpose because along with many ceramics it is lightweight can. Definition of a ceramic material. Polycrystalline materials are formed by multiple.

Composite materials combine two or more materials. Materials science materials science ceramics. Polymers are strong and tough and often flexible. Ceramics are by definition natural or synthetic inorganic non metallic polycrystalline materials.

Ceramic comes from the greek word meaning pottery. Ceramics play an important role in engine efficiency and pollution abatement in automobiles and trucks. 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. However because glass is an amorphous solid glass is usually considered to be a separate material.

Engineering ceramics can be divided into functional ceramics and high strength structural ceramics.
