Ceramics

Solids consisting of inorganic materials and non -metallic materials.
Resulting from the process of forming and hardening using the method of heating at high temperatures.

Examples of Materials that Make Up Ceramics

Metal compounds: Aluminium oxide, \(Al_2O_3\)
Non -metallic compounds: Titanium carbide, \(TiC\)
Semi -metallic compounds: Silicon carbide, \(SiC\)

Types of Ceramics

Traditional Ceramics

Made of clay such as kaolin, \(Al_2O_3.2SiO_2.2H_2O\)
The clay is mixed with water to produce a soft and easily formed mixture.
Then, the mixture is baked at a high temperature.
Typically, traditional ceramics are used in the manufacture of bricks, pottery and crockery.
Generally, traditional ceramics are used to make:
- Brick
- Pottery
- Bowl

Advanced Ceramics

Made from inorganic materials such as oxides, carbides and nitrides.
Has higher heat and abrasion resistance, is more chemically inert and has superconductivity properties.
Silicon carbide:
- Used to make cutting discs that are hard and strong.
- Used to make brake discs due to their thermal shock-resistant properties and high resistance to heat.
Generally, traditional ceramics are used to make:
- Tungsten carbide rings because it is hard and resistant to abrasion.
- Cutting disc
- Tungsten carbide ring

Ceramic Uses Application

Medicine

Zirconia ceramic is used in dental implants.
Alumina ceramic is used to make knee bone.
Ceramic is used in Magnetic Resonance Imaging (MRI) machines because it has superconductivity properties.

Transportation

Engine components in jet planes are made from ceramics.

Energy production

Ceramic is used to make electrical insulators in high voltage areas such as power stations.
