Generally ionic bonds are stronger than covalent bonds. This is because in ionic bonds, electrostatic forces of attractin are involved. The positive ion (cation) and the negative ion (anion) are held together by electrostatic forces of attraction which are very strong. To break an ionic bond, these ions have to be pulled apart which is very difficult due to strong attraction between them.
