Ionic compounds have strong bonds holding the crystal lattice together that are due to the attraction between the oppositely charged cations and anions. Covalent compounds which are made up of discrete molecules (not giant molecular compounds like silica) have only weak intermolecular forces holding the solid form together and therefore these solids are easier to "break up" with thermal energy.

Ionic compounds are crystalline solids at room temperature. It takes a lot of energy to collapse that crystalline lattice structure. This results in high melting points, like around 800 degrees Celsius for salt (sodium chloride.)
Melting requires the breaking of intermolecular forces between particles. Ionic bonds are incredibly strong and difficult to break apart, thus giving ionic solids high melting points.
Because they have strong electrostatic force of attraction between the oppositely charged ions.
Ionic compounds
have higher boiling points than molecular compounds because the bonds that hold them together are stronger and so need more energy to break them.
they have high melting and boilig point due to the strong ionic bonds.
Since ionic compounds form a crystal lattice which is very strong while covalent bonds have weak intermolecular forces therefore requiring less energy to melt it.

There is not a statement available so it is difficult to answer this. Some properties of ionic compounds are high melting points, solid in room temperature, and they are brittle.
Compared to ionic compounds, covalent compounds have relatively low melting and boiling points because covalent bonds are not as strong as ionic bonds, and it is the bonds which hold materials together in the solid, or more solid phases.

Ionic compounds generally have higher melting and boiling points.
-Solid at room temperature -Very high melting points -Conducts electricity when disolved in water
The melting point of a compound cannot determine the bonding structure. As an example, both diamond and sodium chloride have higher melting points than 800 centigrade but are covalent and ionic compounds respectively.
The melting points and boiling points of molecular covalent compounds (ones with discrete molecules) are lower than ionic solids and giant molecule covalent compounds like (silica, SiO2) because the forces that attract them together in the solid and the liquid states (van der waals, hydrogen bonding and dispersion forces) are weaker than ionic (or covalent) bonds.

This is a phase change from solid to liquid which occurs at a fixed temperature when the ionic lattice breaks down. In general ionic compounds are high melting.
