tungstic

Microwave treatment of a solution of tungstic acid, elemental sulfur and monoethanolamine.

Tungstic acid refers to hydrated forms of tungsten trioxide, WO.

Tungstic acid is obtained by the action of strong acids on solutions of alkali metallic tungstates.

When concentrating an ammoniacal solution of tungstic acid (i.e. hydrous WO), the product obtained is ammonium paratungstate.

In 1783, José and Fausto Elhuyar found an acid made from wolframite that was identical to tungstic acid.

In 1781, Carl Wilhelm Scheele discovered that a new acid, tungstic acid, could be made from scheelite (at the time named tungsten).

CaWO, or scheelite, is allowed to react with HCl to produce tungstic acid, which decomposes to WO and water at high temperatures.

Tungsten(VI) oxide, also known as tungsten trioxide or tungstic anhydride, WO, is a chemical compound containing oxygen and the transition metal tungsten.

Cadmium tungstate (CdWO or CWO), the cadmium salt of tungstic acid, is a dense, chemically inert solid which is used as a scintillation crystal to detect gamma rays.
