In ionic compounds, the constituent particles are the ions. As a result, these are held together by the strong ionic bonds and the principle forces are the electrostatic forces that hold the ions together in a crystal lattice. Breaking the crystal lattice means pulling the negative and the positive ions apart, which requires a lot of energy as the electrostatic forces are very strong. Hence the melting and the boiling point of ionic compounds are very high.

Answer:
Ionic compounds have high melting point because in ionic compound cations and ions are held together by strong electrostatic forces of attraction.
Hence large amount of energy is required to overcome these forces.
