What is refractory Metal

As the name suggests, these are the type of metals that are very stubborn in nature. Refractory metals are a group of metals that have great resistance to high temperature and wear.  They are chemically inert and have a relatively high density. The melting point of the refractory metals is above 2000 °C. If we take metals like iron, nickel, and cobalt as the standard for melting point, the melting points of the refractory metals range higher than these. Moreover, these metals remain very hard in the room temperature which gives these an added advantage to be used in different fields.

These are some of the refractory metals that are most commonly used these days in the industries:

  • Tungsten (W)
  • Tantalum (Ta)
  • Molybdenum (Mo)
  • Rhenium (Re)
  • Niobium (Nb)

There are some other refractory metals that has critical application in various industries:

  • Chromium (Cr)
  • Hafnium (Hf)
  • Iridium (Ir)
  • Osmium (Os)
  • Rhodium (Rh)
  • Ruthenium (Ru)
  • Titanium (Ti)

Use of Refractory Metals

Because of the extreme resistance of refractory metals at high temperature and their hard nature, these are ideal for making tools for cutting and drilling. These are also resistant to thermal shock, they won’t expand or crack despite that recurring heating and cooling. The heavy density feature, along with these features make refractory metals good for making electrical and heat resisting equipment. Some of the examples are wire, rebars, foil, and ingots. These metals are also used in nuclear reaction control rods, lubricants, and tools for their corrosion resisting power. These metals either in their pure form or alloy finds their application in various industries, like, aerospace, metal processing, nuclear technology, high temperature vacuum furnace, switchgear, medical, lighting, glass, aerospace, semiconductor, defence, PVD coating and automotive industries.
