Question

Electrical conductivity, thermal conductivity and magnetic properties of ceramic material are
1. very high all the time
2. very low all the time
3. dependent on the material
4. ascertainable, instance to instance

Answer 1

Correct Answer - Option 2 : very low all the time

Properties of Ceramic Material include:

• The melting point is very high
• Low toughness
• Thermal and electrical conductivity is less
• Generally shows non-magnetic behavior
• Elasticity is very low
• Very high Compressive strength and stiffness

 

Important Point:

• Ceramic is an inorganic compound that is made either of oxides, carbides, nitrides, or silicates of metal.
• Examples: glass, cement, tiles, bricks, etc.
• The thermal conductivity of the material is a measure of its ability to conduct heat.
• The electrical conductivity of the material is a measure of its ability to flow current.
