Tungsten, or wolfram, is a chemical element with the symbol w and atomic number 74.The name tungsten comes from the former swedish name for the tungstate mineral scheelite, tungsten which means heavy stone.Tungsten is a rare metal found naturally on earth almost exclusively combined with other elements in chemical compounds rather than alone.It was identified as a new element in 1781.
Computations show that a material made with just the right amounts of hafnium, nitrogen, and carbon would have a melting point of more than 4400 k 7460f.Thats about two-thirds the temperature at the surface of the sun and 200 k higher than the highest melting point ever recorded experimentally.
Tungsten metal has a nickel-white to grayish lustre.Among metals it has the highest melting point, at 3,410 c 6,170 f, the highest tensile strength at temperatures of more than 1,650 c 3,002 f, and the lowest coefficient of linear thermal expansion 4.43 10 6 per c at 20 c 68 f.Tungsten is ordinarily brittle at room.

Tantalum ta, chemical element, bright, very hard, silver-gray metal of group 5 vb of the periodic table, characterized by its high density, extremely high melting point, and excellent resistance to all acids except hydrofluoric at ordinary temperatures.Closely associated with niobium in ores.
The stronger the attractive forces are, the more energy is needed to overcome them and the higher the melting or boiling point.When you click on the download symbol, you will be able to download the graph as an image file or pdf file, save its data, annotate it, and print it.

A new record for the worlds highest melting point molten steel is poured into a crucible, at somewhere around 2,500 degrees fahrenheit, but another.
The melting and boiling points of elements, like many of their physical characteristics, depend largely on their position in the periodic table of elements and therefore on their atomic number.But this is a loose relationship, and other information you can gather from the periodic table of elements helps to determine a given elements melting point.
The chemical element with the highest melting point is tungsten, at 3695 k 3422 c, 6191 f.The often-cited carbon does not melt at ambient pressure but sublimates at about 4000 k a liquid phase only exists above pressures of 10 mpa and estimated 43004700 k.Tantalum hafnium carbide ta4hfc5 is a refractory compound with a very high melting point of 4488 k 4215 c, 7619 f.1.
Tungsten has the highest melting point of all metals and is alloyed with other metals to strengthen them.Tungsten and its alloys are used in many high-temperature applications, such as arc-welding electrodes and heating elements in high-temperature furnaces.
Metal with high melting point top 2.Rhenium re rhenium is a silver-white metal with the second highest melting point 3180 c after tungsten and has the highest boiling point.Commercial rhenium is generally powdered and can be pressed or sintered into a high-density solid in vacuum or hydrogen, with a density of more than 90 of the metal state.
A.Iron b.Tungsten c.Copper d.Silver.Submitted by abdul hayee of all metals in pure form, tungsten has the highest melting point 3422 c, 6192 f, lowest vapor pressure at temperatures above 1650 c, 3000 f, and the highest tensile strength.
Melting point is the temperature at which a solid turns into a liquid.In theory, the melting point of a solid is the same as the freezing point of the liquid the point at which it turns into a solid.For example, ice is a solid form of water that melts at 0 degrees celsius32 degrees fahrenheit and changes to its liquid form.
Melting point notes 1.At normal atmospheric pressure carbon does not melt when heated, it sublimes.I.E.When heated, carbon undergoes a phase change directly from solid to gas.If the pressure is increased to 10 atmospheres carbon graphite is observed to melt at 3550 c.2.
2.Graphite 3652.Graphite ranks 2nd in our list of the materials with the highest melting point in the world.Graphite is an allotrope of carbon, where three other carbon atoms arranged in a honeycomb of hexagons are covalently linked to each other to form covalent molecules.Due to its special structure, it has high-temperature resistance, electrical and thermal conductivity.

The d - block elements with more number of unpaired e - will have high melting point as more number of unpaired e - s present, stronger will be the metallic bond formation.Hence requirement of heat to loosen the bond will be high.26fe4s23d6 24cr4s13d5 25mn4s23d5 25ni4s23d8 so, cr contains more number of unpaired e - s hence has high melting point.
The alkali metals have low melting and boiling points compared to most other metals.Apart from the other alkali metals, only three metals indium, gallium and mercury have lower melting points than lithium.You can see from the graph that lithium, at the top of group 1, has the highest melting point.
