Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDF- Ceramics are hard and brittle and are in the form of amorphous or glassy solids. The bond in these materials is mixed ionic and covalent.
- The electrons are not free to move, hence they are thermal and electrical insulators. At low temperatures, ceramics behave elastically. They do not possess any malleability.
- Due to the above reasons, rings or discs made from ceramic are used as insulators at support poles in the transmission & distribution system.
- A ceramic is a solid material comprising an inorganic compound of metal, non-metal, or metalloid atoms primarily held in ionic and covalent bonds. Common examples are earthenware, porcelain, and brick.
Ceramics have certain properties like
- High melting points so they are highly heat resistant.
- Great hardness and strength.
- Very durable.
- Very low electrical conductivity that’s why they are used as insulators in the transmission system.
- Very low thermal conductivity.
- Very much inert to chemical activities so they are unreactive to other chemicals resulting in a longer lifespan.
