In soil, tungsten metal oxidizes to the tungstate anion.
The resource of over 300,000 tonnes of tungsten metal makes Hemerdon the fourth largest tungsten deposit in the world.
The oxygen attacks the tungsten metal, and the resulting tungsten oxide particles travel to cooler parts of the lamp.
Thorium dioxide was used to control the grain size of tungsten metal used for spirals of electric lamps.
Thus, in various laboratories, pellets of tungsten metal were laid out temptingly.
The dominant application of tungsten fluoride is in semiconductor industry, where it is widely used for depositing tungsten metal in a chemical vapor deposition process.
Tungsten hexchloride can be prepared by chlorinating tungsten metal in a sealed tube at 600C:
The filament in a light bulb is made of a long, incredibly thin length of tungsten metal.
Sometimes called mineral blue, it is a blue solid formed by the reaction of tungsten trioxide, WO, and tungsten metal at 700 C.
Upon heating, it disproportionates to WF and tungsten metal.
