It's called the Pole Adit. And it does have tungsten, a little bit of tungsten, left over, that's the kind of mine it was.

Silicon carbide, SiC (carborundum) is a hard, high melting solid and a well known abrasive.

Cohenite is a naturally occurring iron carbide mineral with the chemical structure (Fe, Ni, Co)3C.

The response to a bad idea like, say, a tungsten light bulb is a better idea. OK?

The mineral form of silicon carbide was named moissanite in honor of Moissan later on in his life.

This is the first time that the plutonium rich carbide fuel has been reprocessed anywhere in the world.

At first, he mistakenly identified the crystals as diamonds, but in 1904 he identified the crystals as silicon carbide.

The environmentalists put their money on chromium, copper, nickel, tin, and tungsten, and picked a time frame of 10 years.

Boron carbide, B4C, on the other hand, has an unusual structure which includes icosahedral boron units linked by carbon atoms.

There is a staff on the boat called carbide fitter, who is responsible to replace sulfur rock and control the volume of water to generating acetylene gas.

In 1898 Adolph Frank and Nikodem Caro decoupled the process and first produced calcium carbide and in a subsequent step reacted it with nitrogen to calcium cyanamide.

Armor Piercing (AP) A hard bullet made from steel or tungsten alloys in a pointed shape typically covered by a thin layer of lead and or a copper or brass jacket.

Alloyed steels, which are sometimes also called special steels and may be considered specialty products, contain small portions of alloying elements such as chromium, cobalt, manganese, molybdenum, nickel, niobium, silicon, tungsten or vanadium.

For example, the authors of The Limits to Growth predicted that before 2013, the world would have run out of aluminum, copper, gold, lead, mercury, molybdenum, natural gas, oil, silver, tin, tungsten, and zinc.

The indigenously developed unique plutonium rich mixed carbide fuel used in the fast breeder test reactor (FBTR) has performed extremely well, having operated past a burn up of 148,000 megawatt day per tonne (MWd t) without a single fuel pin failure.

That message still resonates today, though it was spectacularly wrong. For example, the authors of The Limits to Growth predicted that before 2013, the world would have run out of aluminum, copper, gold, lead, mercury, molybdenum, natural gas, oil, silver, tin, tungsten, and zinc.

Theoretically, all five can decay into isotopes of element 72 (hafnium) by alpha emission, but only 180W has been observed ref to do so with a half life of (1.8 0.2) 1018 years on average, this yields about two alpha decays of 180W in one gram of natural tungsten per year.

The coal comes from Colombia, and costs 300 per ton if Antillana had been able to negotiate with United States manufacturer UCAR, from which it would be able to get the world's best carbide graphite electrode, that raw material would be obtained free, because of the contract undertakings UCAR has with its purchasers.
