yes covalent does
Covalent structures have high melting points because the covalent bonds between atoms are strong and require a significant amount of energy to break. This high energy barrier results in a high melting point for covalent structures.
No they have high melting and boiling points. Don't get confused with simple molecular structures such as water and carbon dioxide which have simple covalent structures. When you heat them you are overcoming the forces BETWEEN THE MOLECULES (intermolecular/van der waals forces of attraction), NOT the actual covalent bonds themselves, like the bond betwen the C and either O in carbon dioxide.
Ionic compounds have higher melting points because the bond olding the ionic crystal together is stronger than the intermolecular forces (van der Waals) holding covalent molecules together. Giant covalent molecules such as dialmond and silicon dioxide have very high melting points because the lattice is held together by stong covalent bonds
Ionic bonds are strong electrostatic forces of attraction between oppositely charged ions, resulting in high melting and boiling points. Covalent bonds involve the sharing of electron pairs between atoms, leading to the formation of molecules with moderate to low melting and boiling points, depending on the type of covalent bond.
A possible compound would be silicon dioxide with giant covalent structure and strong covalent bonds.

Compounds bonded by covalent bonds do not necessarily have low melting points. Some have whereas some don't have.Some polymers and hydrocarbons have very high melting points. But it can be said that they don't have melting points as high as ionic compounds. It is so because ionic bonds are stronger than the covalent bonds.
Because they have interlocking electrons as the different elements' electrons have been 'tangled'

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.
Covalent bonds do not melt. Compounds with covalent bonds melt and the melting point depends primarily on whether there are discrete molecules held together by intermolecular forces (which have lower melting points) or giant covalent networks such as in silica or diamond (which tend to have higher melting points).
This is because they have extremely strong covalent bonds that operate in 3D and firmly hold together all the atoms in the lattice structure. Why the bonds are so strong? Probably (and don't quote me here) because the bonds are extremely stable as a result of hybridisation. Consequently, a lot of energy is required to break or even weaken these bonds, hence the exceptionally high melting and boiling points,
It's due to the facts that simple covalent bonds like single bonds are weaker and longer than others bonds with tighter interactions like pi bonds (double bonds) or ionic bonds. Once the heat is turned up it excites the electrons to move from their bonded positions and the bond breaks
Minerals have high melting points because their atoms are held together by strong chemical bonds that require a lot of energy to break apart. These bonds are typically ionic or covalent, leading to a high degree of coordination and stability within the mineral structure, resulting in a high melting point.
