Ceramics In Other Applications

Lightweight optical components e g silicon carbide mirrors.

Ceramics in other applications.

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. Industrial ceramics are commonly understood to be all industrially used materials that are inorganic nonmetallic solids. Engineering ceramics are used to fabricate components for applications in many industrial sectors including ceramic substrates for electronic devices fig. A ceramic material is an inorganic non metallic often crystalline oxide nitride or carbide material.

Bioceramics like alumina with high density and purity is used to dental implants. Radiators i e cooling systems for space vehicles. 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.

Usually they are metal oxides that is compounds of metallic elements and oxygen but many ceramics. The word ceramics is derived from the greek word keramos which means potter s clay. The applied pressure contributes to the sintering driving force see eq. 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.

4 and tappet heads for use in automotive engines. However many compounds which are classified as ceramics today contain no clay. 3 turbocharger rotors fig. L yongli in ceramic matrix composites 2006.

They withstand chemical erosion that occurs in other materials subjected to acidic or caustic environments. For some high tech ceramic applications like transparent ceramics bioceramics structural ceramics etc it is advantageous to use pressure assisted sintering. Electronic thermal management structures. Modern ceramics can be defined as the compounds of metals and non metals.

There are a number of other applications that are found in the other areas too. Other examples of where advanced ceramics are used include oil free bearings in food processing equipment. Other applications of ceramics in the aerospace industry include brakes bearings seals and other wear resistant components. Ceramic composition and properties atomic and molecular nature of ceramic materials and their resulting characteristics and performance in industrial applications.

7 5 and can considerably benefit densification. Other applications in the area of sintering and firing further high temperature applications in the area of sintering and firing for which schupp provides products components and systems. But it is just this bonding nature of ceramics that directly results in their inherent brittleness and difficulty in machining.
