Of these ingredients much the most important are tungsten and molybdenum.
Production of molybdenum in this country practically began in 1914.
Vanadium is white, and when its surface is polished, it resembles silver or molybdenum more than any other metal.
It had up to this time been confounded with molybdenum sulphide.
European steel men have taken to molybdenum more than Americans.
molybdenum high-speed steel is more expensive than tungsten high-speed steel, but is said to wear better.
From sulphuret of molybdenum, dissolved in nitric acid, and some tin filings and a little muriatic acid added.
The chief ore minerals are molybdenite (molybdenum sulphide) and wulfenite (lead molybdate).
molybdenum blue is a combination of this metal, and oxide of tin or phosphate of lime.
Now when we discover a new mineral we dub it "molybdenum" and let it rust in innocuous ease.
metallic element, 1816, from molybdena, used generally for lead-like minerals, from Greek molybdos "lead," also "black graphite," related to Latin plumbum "lead" (see plumb (n.)), and like it probably borrowed from a lost Mediterranean language, perhaps Iberian. The element so called because of its resemblance to lead ore.
molybdenum mo·lyb·de·num (mə-lĭb'də-nəm)
A hard metallic element that is an essential trace element in plant and animal nutrition. Atomic number 42; atomic weight 95.94; melting point 2,623°C; boiling point 4,639°C; specific gravity 10.22 (at 20°C); valence 2, 3, 4, 5, 6.
A hard, silvery-white metallic element that resists corrosion and retains its strength at high temperatures. It is used to harden and toughen steel and to make high-temperature wiring. Molybdenum is an essential trace element in plant metabolism. Atomic number 42; atomic weight 95.94; melting point 2,617°C; boiling point 4,612°C; specific gravity 10.22 (at 20°C); valence 2, 3, 4, 5, 6. See Periodic Table.
