2021-12-13 · Melting Point of Materials. In general, melting is a phase change of a substance from the solid to the liquid phase. The melting point of a substance is the temperature at which this phase change occurs. The melting point also defines a condition in which the solid and liquid can exist in equilibrium. Adding a heat will convert the solid into a ...
The melting point of a material is primarily related to bond strength. Materials with strong bonds between atoms will have a high melting temperature. However, other factors--such as crystal structure, atomic weight, and electron structure--can also influence the melting point. Tungsten, rhenium, osmium, tantalum, and molybdenum are among the highest melting point metals.
