(I) Any material made by firing non-metallic, inorganic
substances at high temperature is called a ‘ceramic’.
(II) Ceramics have diverse applications in industry and
perhaps the oldest examples of their use are in the
making of pottery, and later fine china. (III) The electrical
properties of ceramics mean that they may be used as
the dielectric material in devices used to store an
electrical charge. (IV) Although renowned for their
strength, hardness and durability, ceramics are often
fragile and need careful handling. (V) In addition, their
heat tolerance makes them ideal for use in home
heating systems and components for engines in
vehicles.
