Tungstic acid is primarily used in the production of tungsten metal and its compounds. It serves as a precursor in the synthesis of tungsten oxides, which are essential in manufacturing tungsten carbide, a material widely used in cutting tools, abrasives, and wear-resistant parts.

In the field of catalysis, tungstic acid is employed as a catalyst or catalyst support in various chemical reactions, including oxidation and dehydration processes. It is also utilized in the preparation of phosphotungstic acid, a compound used in analytical chemistry and as a catalyst in organic synthesis.

Additionally, tungstic acid finds applications in the textile industry, where it is used in the production of fireproof and waterproof fabrics. It is also employed in the creation of pigments and dyes, contributing to the coloration of ceramics and glass.

In the realm of electronics, tungstic acid is used in the fabrication of electronic components, such as semiconductors and capacitors, due to its electrical properties. Its role in these applications underscores its importance in advancing technology and industrial processes.
