As we all know, the melting point is the temperature at which substance converts from solid-state to liquid state. Some of the metals show very high melting points at least 2,000 degrees Celsius, and they also have very high physical strength. These metals are named as refractory metals. Niobium, molybdenum, tantalum, tungsten, and rhenium are refractory metals.
Many metals have some important characteristics, including hardness, ductility, malleability, tensile strength, density, and melting point, their properties cannot be shown by non-metals.
The high melting point of elements is due to strong intermolecular forces between atoms. Metals are mainly involved in metallic bonds which are an electrostatic force of attraction between metal ions and free electrons in their crystal lattice.
Tungsten and molybdenum are the most common refectory metals. Because of their high-temperature tolerance, they are used in a variety of equipment such as bulbs.
Tantalum, iridium, platinum, gold, tungsten, hafnium, and silver are heavy metals. The closely packed metallic structures show a high melting point. For example, tungsten is a metal with the highest melting point. So, the filament of a bulb is made from tungsten. Tungsten melts at extremely high temperatures that are 3,380 degrees Celsius whereas cesium has a very low melting point of 28.5°C.
There is a list of high melting point elements as follows:
