17 Metals With the Highest Melting Points (and Why

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.

Silicon Carbide - an overview | ScienceDirect Topics

If silicon carbide cannot be polished efficiently at a high precision level, it becomes difficult to use this material in any optical or electrical device. As a nonmechanical or noncontact method of machining, CO 2 lasers can be used to directly machine silicon carbide without needing to worry about tool wear or low removal efficiency [5] .
