Tungsten carbides (W2C and WC) are produced by heating powdered tungsten with carbon.

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.

Tungsten compounds are also often used as industrial catalysts.

Precautions Because tungsten is rare and its compounds are generally inert, the effects of tungsten on the environment are limited.

Other salts that contain tungsten are used in the chemical and tanning industries.

The low thermal expansion and high melting point and tensile strength of tungsten originate from strong covalent bonds formed between tungsten atoms by the 5d electrons.

Some types of strings for musical instruments are wound with tungsten wires.

He named the mineral tungsten, meaning heavy stone in Swedish.

Hard materials Tungsten is mainly used in the production of hard materials based on tungsten carbide, one of the hardest carbides, with a melting point of 2770 C.

In electronic equipment, thorium coating of tungsten wire improves the electron emission of heated cathodes.

Its high melting point also makes tungsten suitable for aerospace and high temperature uses such as electrical, heating, and welding applications, notably in the gas tungsten arc welding process (also called tungsten inert gas (TIG) welding).

In English, this metal is now known as the element tungsten.

These are known as bronzes an example is sodium tungsten bronze.

A good example is high speed steel, which can contain as much as 18 tungsten.

Patent claim Tungsten is unique amongst the elements in that it has been the subject of patent proceedings.

These include iron, uranium, aluminium, nickel, platinum, tungsten, titanium, and copper.

Thoria was used to control the grain size of tungsten metal used for spirals of electric lamps.

The fibers can be produced by chemical vapor deposition of boron on a tungsten filament.

W2C is resistant to chemical attack, although it reacts strongly with chlorine to form tungsten hexachloride (WCl6).

The metatungstate ion exists as a symmetric cluster of twelve tungsten oxygen octahedra known as the Keggin anion.

The light grid will have a light, be lit up at night and give a kind of light ceiling.

Economy Chukotka has large reserves of oil, natural gas, coal, gold, and tungsten, which are slowly being exploited, but much of the rural population survives on subsistence reindeer herding, whale hunting, and fishing.

Deposits of nickel, tin, chromite, uranium, bauxite, beryllium, copper, lead, tungsten, zinc, gold, and other minerals are exploited.

Chemical applications Tungsten(IV) sulfide is a high temperature lubricant and is a component of catalysts for hydrodesulfurization.

The chemistry and the compounds show more similarity to those of tungsten than that of chromium.

As you would expect, it's a light, a desk lamp.

An example is the instability of molybdenum(III) and tungsten(III) compounds as compared with the stability of the chromium(III) compounds.

The most common formal oxidation state of tungsten is 6, but it exhibits all oxidation states from 2 to 6.

Tungsten oxides are used in ceramic glazes and calcium magnesium tungstates are used widely in fluorescent lighting.

Festival of lighting

Because of its lower density and more stable price, molybdenum is sometimes used instead of tungsten.

Other major natural resources in production include lead, tungsten, graphite, magnesite, gold, pyrites, fluorspar, and hydropower.

It's light, and light has been around for many millions of years.

He would shoot his light saber across the abyss, making a blade of light, and then scamper across on this blade of light.

In World War II, molybdenum again saw strategic importance as a substitute for tungsten in steel alloys.

God said, Let there be light, and there was light.

I need some light.

Tungsten is the only metal from the third transition series that is known to occur in biomolecules, where it is used in a few species of bacteria and archaea.

In electronics, tungsten is used as an interconnect material in integrated circuits, between the silicon dioxide dielectric material and the transistors.

It is used in metallic films, which replace the wiring used in conventional electronics with a coat of tungsten (or molybdenum) on silicon.

Life evolved under conditions of light and darkness, light and then darkness.

Electromagnetic radiation in this range of wavelengths is called visible light or simply light.

Refractory metals such as tantalum and tungsten along with the more stable oxides, borides, carbides, nitrides and silicides can tolerate this.

The color temperature of a light source is the temperature of an ideal black body radiator that radiates light of comparable hue to that of the light source.

Shade light shines a distant light on an image to create a three dimensional effect.
