Tungstic acid is a precursor of tungsten powders used for many applications, including the production of cutting tools, anti-corrosion coatings, cores, etc. It is used in the textile industry, in the production of tungsten fibers, plastic masses and pigments. Also used for mortars, analytical reagents, catalysts, water treatment agents, production of fireproof and waterproof materials and boron tungstate, etc.

Used to produce metallic tungsten, tungstic acid, etc.

Used in mordants, pigments, dyes and inks.
