Because an ionic bond is very stable, so it needs a larger amount of thermal energy to break its bond.
its simple. ionic compounds have strong electrovalent bonds which need more heat to be broken down. hence more heat is needed to convert the solid into its other state. therefore high melting and boiling point.
Ionic compounds generally have a higher melting point. This is because the bonds between the negative and positive ions are strong, and this keeps the solid together as the temperature rises. Covalent compounds have comparatively weak bonds between the molecules, so as the temperature rises, these bonds are broken easily and the substance turns into a liquid.
ionic bond
Chemicals have boiling points, bonds do not. But let us say, you are asking what the boiling point is of a chemical that has an ionic bond. Again, not all ionic type chemicals (which are generally called salts) have the same boiling point. I can, however, tell you that the boiling point of a salt tends to be very high, in the thousands of degrees.
Potassium chloride has an ionic bond.
These are melting point, boiling point, hardness.

an ionic bond
measurable you can measure it and observable you can see and observe it
An ionic bond exists when one element donates its electrons to the other element in the bond. It is not a true bond but rather an electrostatic attraction (the + of one is attracted to the - of the other) Ionic bonds occur if there is a great difference in electronegativity (greater than 1.7 in the pauling scale). Usually they will occur with a alkaline metal (1A element - very low electronegativity) and a halogen (7A - very electronegative.) Some properties are that they disassociate in water (depressing the freezing point raising the boiling point and making the liquid conductive). They form crystal complexes and do not truly exist as a molecule rather as an ionic solid with no definable beginning or end. They therefore do not have a molecular formula but rather just an empirical formula representing their ratio.

well acuttaly a boiling point is higher because the boiling point is at 100 degrees and like so a melting point is a 0 degrees and a boiling point the particles spread out quicker but the melting point the particles are a strong bond so cannot be squahsed and are at a lower rate of temprrature/heat
The ionic bond is stronger.
This is because of the strong force of attraction between the positively and negatively charged ions in the ionic lattice
