Ceramic Uses In Engineering

Ceramics are also used at many places in gas turbine engines.

Ceramic uses in engineering.

It has for many years been used for cutting tools dies rock drills and as an abrasive. A ceramic material is an inorganic non metallic often crystalline oxide nitride or carbide material. Alumina aluminium oxide al 2 o 3 is by far the most commonly used engineering ceramic and is generally specified as the ceramic of. The thermal stability wear resistance and resistance to corrosion of ceramic components make the application of ceramic the ideal choice for many industrial uses.

These material properties are utilized to produce number of commercial and domestic products such as pottery bricks advanced functional items etc. Its toughness k c and the size distribution of microcracks it contains. Ceramic engineering like many sciences evolved from a different discipline by today s standards. 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.

They withstand chemical erosion that occurs in other materials subjected to acidic or caustic environments. The strength of a ceramic is largely determined by two characteristics. Types of engineering ceramics. 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.

As a result they are used to make pottery bricks tiles cements and glass. Diamond the synthetic variety is the ultimate engineering ceramic. Ceramics can be organised into types or categories in terms of composition oxide carbide and so on. Picture courtesy of nasa on the commons.

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. 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. Bio ceramics are used as dental implants and synthetic bones.

Ceramic products are hard porous and brittle. 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. The characteristics of some of the more common are given below. Given below are some other important uses of ceramics.

Ceramic materials can be identified by their general properties like high hardness brittleness chemical stability and low thermal conductivity. Ceramic tiles helped to protect the space shuttle from heat when it came back into earth s atmosphere. But it is extremely expensive. Advanced ceramics and traditional ceramics are the main categories of ceramic materials.
