Covalent Crystals
Covalent (or network) solids are extended-lattice compounds, in which each atom is covalently bonded to its nearest neighbors.
The rearranging or breaking of covalent bonds requires large amounts of energy; therefore, covalent solids have high melting points.

Answer:
Covalent crystals tend to be hard and to have very high melting points because of the strong attractions between covalently bonded atoms. They do not conduct electricity because the electrons are bound too tightly to the bonds.
Question :
What are the main characteristics of covalent bonds?
Answer :
Covalent compounds have bonds where electrons are shared between atoms. Due to the sharing of electrons, they exhibit characteristic physical properties that include lower melting points and electrical conductivity compared to ionic compounds.
