Boron Carbide | Density, Strength, Hardness, Melting Point

Boron Carbide – Melting Point. Melting point of Boron Carbide is 2427 °C. Note that, these points are associated with the standard atmospheric pressure. 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.
