Ceramic materials are inorganic non metallic materials made from compounds of a metal and a non metal.
Types of ceramics and their properties.
In this lesson we will learn about the different types of ceramics and the uses of these ceramics.
There s quite a big difference between age old general purpose.
Usually they are metal oxides that is compounds of metallic elements and oxygen but many ceramics.
A ceramic material is an inorganic non metallic often crystalline oxide nitride or carbide material.
Ceramic materials may be crystalline or partly crystalline.
They are mainly of two types based on their atomic structure.
They can also be classified into three different material categories.
Ceramics are by definition natural or synthetic inorganic non metallic polycrystalline materials.
Ceramics tend to be rigid and brittle i e not capable of much plastic deformation.
Sometimes even monocrystalline materials such as diamond and sapphire are erroneously included under the term ceramics.
They may be as much as 96 gas by volume.
However their properties depend both on temperature and on the amount of crystallinity.
They are formed by the action of heat and subsequent cooling.
Ceramic composition and properties atomic and molecular nature of ceramic materials and their resulting characteristics and performance in industrial applications.
Ceramic foams are generally less strong than a solid ceramic but may be very strong relative to their weight.
They withstand chemical erosion that occurs in other materials subjected to acidic or caustic environments.
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.
This is called a compound.
Most ceramics are made up of two or more elements.
Highly electricity resistance.
The properties of ceramic materials like all materials are dictated by the types of atoms present the types of bonding between the atoms and the way the atoms are packed together.
This is known as the atomic scale structure.
The properties of ceramics however also depend on their microstructure.
Lower temperatures and higher crystallinity content tend to increase the modulus and the brittleness.
Let s look at each effect separately.
In chemistry ceramics refer to more than simply pottery and plates.
