Ceramics

 
8.3  Ceramics
 
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, \(SiC\)
 
The image is an infographic titled ‘Basic Properties of Ceramics.’ It features a central box with this title, surrounded by six other boxes connected to it. Each of the surrounding boxes lists a property of ceramics: ‘Heat insulator,’ ‘High heat resistance,’ ‘Fragile,’ ‘Chemically inert’ ‘Electrical insulation,’ and ‘Hard and strong.’ The design uses shades of blue and white, with the logo ‘Pandai’ at the bottom right corner.
 
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.
