Tungsten oxide information

Tungsten has several oxidation states, and therefore oxides: Tungsten(III) oxide Tungsten(IV) oxide, also known as tungsten dioxide Tungsten(VI) oxide...

Tungsten(VI) oxide, also known as tungsten trioxide is a chemical compound of oxygen and the transition metal tungsten, with formula WO3. The compound...

divided tungsten is pyrophoric. The most common formal oxidation state of tungsten is +6, but it exhibits all oxidation states from −2 to +6. Tungsten typically...

occurs in some transition metal oxides which conduct both electrons and ions, such as tungsten trioxide (WO3). These oxides have octahedral structures of...

but in an oxygen containing atmosphere (air) then instead of tungsten, a tungsten oxide layer is produced. The deposition process occurs at temperatures...

attacks the tungsten metal, and the resulting tungsten oxide particles travel to cooler parts of the lamp. Hydrogen from water vapor reduces the oxide, reforming...

by the reaction of tungsten trioxide, WO3, and tungsten metal at 700 °C. There are a number of these unusual intermediate oxides formed from reacting...

one oxygen is unconstrained (an atom that is bonded only to the central tungsten (W) atom), and the three other oxygens are each bonded to a zirconium atom...

The metal–oxide–semiconductor field-effect transistor (MOSFET, MOS-FET, or MOS FET) is a type of field-effect transistor (FET), most commonly fabricated...

tungstate can also be prepared by the reaction of nickel(II) oxide and tungsten(VI) oxide. It can also be obtained by the reaction of ammonium metatungstate...

temperature, tungsten reacts to form tungsten(VI) oxide, which volatilizes away, and hydrogen. Hydrogen then reacts with tungsten oxide, after which water...

The melting point of thorium oxide is 3300 °C – the highest of all known oxides. Only a few elements (including tungsten and carbon) and a few compounds...

Tungstite is a hydrous tungsten oxide mineral with formula: WO3·H2O. It is a secondary mineral formed by the weathering of other tungsten containing minerals...

with metal oxides. It is heated by a tungsten filament inside it, and the heat from the filament causes the outside surface of the oxide coating to emit...

the gate oxide is a thin electrode layer made of a conductor which can be aluminium, a highly doped silicon, a refractory metal such as tungsten, a silicide...
