Preface
Writing background and significance
Tungstic acid (chemical formula H₂WO₄ ) is one of the most basic and structurally diverse inorganic acids in the tungsten chemical system. Since it was first separated in the 19th century, it has gradually evolved into a core intermediate in modern tungsten material science, inorganic synthetic chemistry and functional material technology. It is not only an important precursor for a variety of tungsten compounds (such as tungstates, metatungstates, tungstates and tungsten oxides), but also a class of functional materials with potential application value.
In key strategic areas such as energy transformation, new material development, and green chemistry, tungstic acid and its derivatives have shown broad application prospects. For example, in emerging applications such as photocatalytic degradation, water treatment, supercapacitors, and electrochromic devices, tungstic acid has attracted much attention due to its excellent redox ability, multi-level crystal structure, and ion migration characteristics. In addition, tungstic acid also has an irreplaceable position in traditional industries such as inorganic salt preparation, tungsten metal extraction, high-temperature ceramic synthesis, and chemical analysis reagents.
With the continuous advancement of the global “localization of high-performance metal materials”, “green metallurgy” and “new energy driven material transformation”, tungstic acid, as a key node connecting tungsten resources and high-end functional materials, its comprehensive performance, preparation technology, application path, environmental impact and market potential urgently need to be systematically sorted out and deeply studied.
In this context, the compilation of the “Encyclopedia of Tungsten Acid” is not only intended to summarize the current research results and industrial practices in the field of tungsten acid at home and abroad, but also to provide scientific research institutions, engineering and technical personnel, high-end user companies and policy decision-making departments with an authoritative, systematic and operational knowledge framework and technical basis.
The strategic value of tungstic acid
The importance of tungstic acid can be understood from the following four dimensions:
- Strategic resource bridge role
Tungstic acid is the transition form between APT (ammonium paratungstate) to tungsten metal and tungsten oxide, and occupies a key position in the tungsten industry chain. - Material R&D Platform Characteristics
Tungsten acid has material engineering capabilities such as regulating crystal form, doping metal ions, and constructing porous structures. It is an important platform molecule for the preparation of nano- tungsten materials, multi-acid coordination structures, and composite catalytic materials. - Green manufacturing and functional applications are compatible with
its water solubility and controllable precipitation, making it suitable for wet green preparation routes and meeting the requirements of energy conservation and emission reduction. At the same time, tungstic acid and its salts have multifunctional conductivity, photocatalysis, thermal stability and other properties, and have both scientific research and application value. - The basic unit for building international discourse power.
At present , the export control of tungsten resources is gradually strengthened. Tungsten acid and its extended products have become an important export form of China’s strategic metal resources “going out”. The relevant standardization and industrialization level directly affect China’s discourse power in the international supply chain of high-end materials.
