 A solid made up of inorganic and non-metallic

substances.Ex: Porcelain, Stoneware, Earthenware

 Produced through the process of shaping and

hardening by using heating technique.

 Ceramics are mostly made up of metal
compounds,non-metal compounds or metalloid
compounds.

 Ceramics have high thermal resistance. The
atoms in ceramics are bonded by strong covalent
bonds and ionic bonds.So,it only melts at high
temperatures. It is also considered as a heat
insulator.

 Ceramic are hard and strong because the atoms
in ceramic cannot slide over each other. The
force applied to ceramics, is used to break the
bonds. Thus, ceramics are brittle and weak

 Ceramics are chemically inert. Ceramics are also
an electrical insulator. The electrons in ceramics

cannot move freely to conduct electricity or
heat.



 Made from clay such as kaolin. Clay is mixed
with water to produce a soft, moldable
mixture. The mixture is then heated at a
very high temperature. Generally, traditional
ceramics are used to make bricks, pottery
and crockery.

 Advanced ceramics are made from inorganic
compounds such as oxides, carbides and
nitrides. It have higher resistance to heat and
abrasion, more chemically inert and have
superconductivity properties. Advanced
ceramics such as silicon carbide are used to
make cutting disc due to its hard and strong
properties. Its is also used to make brake disc
because it can withstand thermal shocks and
have high resistance to heat.

 Engine components in jet planes are made from
Ceramics.

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

 Ceramic is used in (MRI) machines because of its
Superconductivity properties.

 Roofs, bathroom and kitchens are covered with
ceramics tiles.

 Cooking item such as crockery and pots are mostly
made from ceramics.
