Ceramics can be defined as heat-resistant , non-metallic , inorganic solids that are generally made up of compounds formed from metallic and non-metallic elements.
Although different types of ceramics can have different properties , in general ceramics are corrosion-resistant and hard , but brittle.
Most ceramics are also good insulators and can withstand high temperatures.
These properties have led to their use in virtually every aspect of life.
The two main categories of ceramics are :--- Traditional and Advanced
Traditional ceramics include objects made of clay and cements that have been hardened by heating at high temperatures.
These are used in dishes , crockery , flowerpots..e.t.c.
Advanced ceramics include carbides such as silicon carbide ( SiC ) e.t.c.
These act as good superconductors that is why they are used in making sockets..e.t.c.
