Ceramics In Other Applications

Bioceramics like alumina with high density and purity is used to dental implants.

Ceramics in other applications.

Other applications of ceramics in the aerospace industry include brakes bearings seals and other wear resistant components. But it is just this bonding nature of ceramics that directly results in their inherent brittleness and difficulty in machining. Today the outer most border of human progress is where we perfectly control and use the highest temperatures. The word ceramics is derived from the greek word keramos which means potter s clay.

Engineering ceramics are used to fabricate components for applications in many industrial sectors including ceramic substrates for electronic devices fig. 7 5 and can considerably benefit densification. However many compounds which are classified as ceramics today contain no clay. Radiators i e cooling systems for space vehicles.

4 and tappet heads for use in automotive engines. Martin trunec karel maca in advanced ceramics for dentistry 2014. Industrial ceramics are commonly understood to be all industrially used materials that are inorganic nonmetallic solids. They withstand chemical erosion that occurs in other materials subjected to acidic or caustic environments.

The applied pressure contributes to the sintering driving force see eq. L yongli in ceramic matrix composites 2006. 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. Lightweight optical components e g silicon carbide mirrors.

Other types of electroceramics consist primarily of ferrite based permanent magnets and circuit devices for high reliability applications e g low and high temperature co fired ceramics and ceramic electronic substrates. They generally have ionic atomic bonding between them. Magnetic ceramics are another type of advanced ceramic material that is used for the production of antennas and inductors. There are a number of other applications that are found in the other areas too.

The application of ceramics has infiltrated almost all fields in the last 20 years because of their advantages over metals due to their strong ionic or covalent bonding. Modern ceramics can be defined as the compounds of metals and non metals. Ceramic composition and properties atomic and molecular nature of ceramic materials and their resulting characteristics and performance in industrial applications. Other examples of where advanced ceramics are used include oil free bearings in food processing equipment.

For some high tech ceramic applications like transparent ceramics bioceramics structural ceramics etc it is advantageous to use pressure assisted sintering. Usually they are metal oxides that is compounds of metallic elements and oxygen but many ceramics. 3 turbocharger rotors fig.
