Vanadium is a chemical element originated from Vanadis, an old Norse name for the Scandinavian goddess Freyja. It was first mentioned in 1801 and observed by M. del RÃo. The isolation was later accomplished and announced by N.G.SefstrÃ¶m. “V” is the canonical chemical symbol of vanadium. Its atomic number in the periodic table of elements is 23 with location at Period 4 and Group 5, belonging to the d-block. The relative atomic mass of vanadium is 50.9415(1) Dalton, the number in the brackets indicating the uncertainty.
Tungsten, also called wolfram; wolframium, is a chemical element originated from the Swedish ‘tung sten’ meaning heavy stone(W is wolfram, the old name of the tungsten mineral wolframite). It was first mentioned in 1781 and observed by T. Bergman. The isolation was later accomplished and announced by J. and F. Elhuyar. “W” is the canonical chemical symbol of tungsten. Its atomic number in the periodic table of elements is 74 with location at Period 6 and Group 6, belonging to the d-block. The relative atomic mass of tungsten is 183.84(1) Dalton, the number in the brackets indicating the uncertainty.

I only needed one piece of sputtering target each and this was the smallest pack i could find (pack of 2). needless to say, I'm very pleased with what I received 🙂 they seem to be really good quality
