Compared with metals, ceramics generally have:

1. Higher hardness and melting points but lower toughness
2. Higher ductility and lower hardness
3. Higher electrical conductivity
4. Lower compressive strength

Answer

A. Higher hardness and melting points but lower toughness

Solution

Ionic/covalent bonding gives hardness and stability but brittleness.
