Ionic compounds generally have high melting points because:
Inter-ionic electrostatic forces are strong
Ionic compounds are held together in a rigid crystal lattice by strong electrostatic forces of attraction between oppositely charged ions. Breaking this lattice to melt the compound requires a large amount of thermal energy, which is why ionic compounds generally have high melting points.
