Melting point of covalent solids
WebTo break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically characterized by hardness, strength, and high melting points. For example, diamond is one of the hardest substances known and melts above 3500 °C. http://hyperphysics.phy-astr.gsu.edu/hbase/Chemical/bond2.html
