Ceramic Uses In Engineering

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.

Ceramic uses in engineering.

Ceramic may be used as a noun in the singular to refer to a ceramic material or the product of ceramic manufacture or as an adjective. Engineering ceramics are those which have been specially produced to create ceramic components to provide solutions for engineering conditions with specialist requirements. Aluminium oxide al 2 o 3 and zirconia zro 2 are the most commonly used engineering grade oxide ceramics with alumina being the most used ceramic by far in terms of both tonnage and value. Ceramics is the making of things out of ceramic materials.

Ceramics can be organised into types or categories in terms of composition oxide carbide and so on. They withstand chemical erosion that occurs in other materials subjected to acidic or caustic environments. Its specific electrical resistance reaches 10 16 ω cm at room temperature while at 1600 c it still reaches a level of 10 6 ω cm. Diamond the synthetic variety is the ultimate engineering ceramic.

Ceramic materials can be identified by their general properties like high hardness brittleness chemical stability and low thermal conductivity. Ceramics are also used at many places in gas turbine engines. Alumina aluminium oxide al 2 o 3. Ceramic products are hard porous and brittle.

Ceramic engineering like many sciences evolved from a different discipline by today s standards. It has for many years been used for cutting tools dies rock drills and as an abrasive. The strength of a ceramic is largely determined by two characteristics. Picture courtesy of nasa on the commons.

Al 2 o 3 ceramic with purity up to 99 9 remains one of the most commonly used oxide ceramic electrical insulating materials even today. Silicon nitride si 3 n 4 and aluminium nitride aln are the main advanced engineering ceramics in this category there is a wide range of grades and types of these materials. Bio ceramics are used as dental implants and synthetic bones. Its toughness k c and the size distribution of microcracks it contains.

Advanced ceramics and traditional ceramics are the main categories of ceramic materials. A ceramic material is an inorganic non metallic often crystalline oxide nitride or carbide material. Given below are some other important uses of ceramics. If aerospace is an extraordinary use for extraordinary ceramics construction is one of the best known uses for ordinary everyday ceramics.

The characteristics of some of the more common are given below. Ceramic tiles helped to protect the space shuttle from heat when it came back into earth s atmosphere. Alumina aluminium oxide al 2 o 3 is by far the most commonly used engineering ceramic and is generally specified as the ceramic of. As a result they are used to make pottery bricks tiles cements and glass.
