Key Physical Properties Of Ceramics

Sometimes even monocrystalline materials such as diamond and sapphire are erroneously included under the term ceramics.

Key physical properties of ceramics.

Composite materials combine two or more materials. Ceramics are hard and strong but brittle. The properties of ceramics however also depend on their microstructure. In the following module we will focus on brittle fracture of ceramic materials.

Here we classify ceramics into five properties. Ceramics usually withstand high temperature but it has poor mechanical properties. Industrial ceramics are commonly understood to be all industrially used materials that are inorganic nonmetallic solids. 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.

Development of ceramics helps to decrease the demand in industries. Ceramics play an important role in our day to day life. Different materials have different properties. There s quite a big difference between age old general purpose.

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. Ceramics are by definition natural or synthetic inorganic non metallic polycrystalline materials. Compare to other materials ceramics have some unique properties. Usually they are metal oxides that is compounds of metallic elements and oxygen but many ceramics.

We will approach all of the major categories of ceramic properties in this module physical chemical and mechanical with key examples for each one. Ceramic composition and properties atomic and molecular nature of ceramic materials and their resulting characteristics and performance in industrial applications.
