A ceramic material is an inorganic non metallic often crystalline oxide nitride or carbide material.
Important properties of ceramic materials.
Ceramics are compounds of metals and non metals.
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.
Most ceramics are made up of two or more elements.
The density of ceramics is intermediate between polymers and metals.
What is a ceramic.
Ceramic composition and properties atomic and molecular nature of ceramic materials and their resulting characteristics and performance in industrial applications.
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.
These material properties are utilized to produce number of commercial and domestic products such as pottery bricks advanced functional items etc.
These are very important parameters for the ceramic material.
Crystalline materials have high density than non crystalline materials.
We determine the above all properties with the particle sizes of the material.
They have ionic atomic bonding they include insulating materials glass refractories abrasives enamels.
Usually they are metal oxides that is compounds of metallic elements and oxygen but many ceramics.
Ceramic materials can be identified by their general properties like high hardness brittleness chemical stability and low thermal conductivity.
Generally ceramic particles are fine and coarse.
They withstand chemical erosion that occurs in other materials subjected to acidic or caustic environments.
These highly desirable properties of ceramics have as yet been largely disregarded due to the perceived low toughness and brittle failure demonstrated by traditional ceramic strength however recent developments have led to a new breed of ceramic materials displaying mechanical properties that were previously considered.
Industrial ceramics are commonly understood to be all industrially used materials that are inorganic nonmetallic solids.
Advanced ceramics and traditional ceramics are the main categories of ceramic materials.
