That would be Tungsten. it melts at 3410 celcius. there’s probably tungsten in the room you’re in right now – in the light bulb! Because it has such a high melting point, we can pass lots of electrical current through it (which heats it)to generate light before it melts away.
Yep, its Tungsten, which is the 2nd hardest material (after diamonds). In fact, that’s why its called tungsten! In Norwegian, ‘tung’ means heavy, and ‘sten’ means stone. So its name literally means ‘heavy stone’!
Tungsten at 3410 C so it found use in the incandescent light bulbs that were commonly used up until a couple of years ago. The filament (i.e. the part of the bulb that glows and generates the light) was made of tungsten. Now this type of light bulb technology is not in the market any more as it was producing little light compared to the amount of electricity that was using.
