melting temperatures, form oxides with low melting points (TiO 2 – T m = 1840°C and Nb 2O 5 – T m = 1485°C). Graphite has the highest melting temperature of any material known, but starts to burn thet 800°C. While it is a most widely used material in high-temperature appliions, it must be protected by coatings for long-term use.

Melting point | chemistry | Britannica

Melting point, temperature at which the solid and liquid forms of a pure substance can exist in equilibrium. As heat is applied to a solid, its temperature will increase until the melting point is reached. More heat then will convert the solid into a liquid with no temperature change. When all the
