Key Physical Properties Of Ceramics

People first started making ceramics thousands of years ago pottery glass and brick are among the oldest human invented materials and we re still designing brand new ceramic materials today things like catalytic converters for today s cars and high temperature superconductors for tomorrow s computers.

Key physical properties of ceramics.

Ceramics play an important role in our day to day life. Industrial ceramics are commonly understood to be all industrially used materials that are inorganic nonmetallic solids. Ceramic composition and properties atomic and molecular nature of ceramic materials and their resulting characteristics and performance in industrial applications. Development of ceramics helps to decrease the demand in industries.

Ceramics are an incredibly diverse family of materials whose members span traditional ceramics such as pottery and refractories to the modern day engineering ceramics such as alumina and silicon nitride found in electronic devices aerospace components and cutting tools. Composite materials combine two or more materials. Whilst the most extravagant claims of the 1980s in favour of advanced ceramic materials such as the all ceramic engine. Usually they are metal oxides that is compounds of metallic elements and oxygen but many ceramics.

Compare to other materials ceramics have some unique properties. Sometimes even monocrystalline materials such as diamond and sapphire are erroneously included under the term ceramics. Ceramics are hard and strong but brittle. Ceramics are by definition natural or synthetic inorganic non metallic polycrystalline materials.

There s quite a big difference between age old general purpose. In the following module we will focus on brittle fracture of ceramic materials. Polymers are strong and tough and often flexible. Here we classify ceramics into five properties.

Polycrystalline materials are formed by multiple. Ceramics usually withstand high temperature but it has poor mechanical properties.
