Why does potassium chloride have a high melting point?

Potassium chloride is an ionic compound. The bond holding the atoms together is known as ionic bond. Strictly speaking it is NOT a discrete molecule of K + Cl- but a crystal lattice consisting of each K+ surrounded by Cl- ions and vice versa. The bonds in this lattice all have to be broken to melt the compound. There is a strong electrostatic force of attraction between the chloride ions and the potassium ions. A large amount of heat energy has to be applied to break the strong bond holding the atoms, resulting in the compound having a high melting point.
