1.1 Purpose and significance of compiling the Sodium Tungstate Encyclopedia
Sodium tungstate plays a key role in tungsten metallurgy, petrochemical industry, sewage treatment and diabetes research due to its excellent chemical stability, catalytic performance and biological activity. However, the existing literature is mostly presented in a scattered form and lacks systematic integration. This book aims to fill this gap and bring together the chemical properties, preparation methods, application fields, scientific research, industrial status and environmental impact of sodium tungstate, providing a one-stop resource for academic research and industrial applications. This book not only sorts out the theoretical and practical knowledge of sodium tungstate, but also looks forward to its development potential in cutting-edge fields such as new energy and nanotechnology, and strives to promote innovation and sustainable development in related fields.
1.2 Overview of the History and Development of Sodium Tungstate
The discovery and application of sodium tungstate can be traced back to the early 19th century, when chemists first synthesized sodium tungstate by extracting tungstic acid from tungsten ore and reacting it with sodium salt. In the early days, sodium tungstate was mainly used in analytical chemistry as a reagent for the determination of phosphates and proteins. In the 20th century, with the development of the tungsten metallurgical industry, sodium tungstate became an important intermediate for the production of ammonium paratungstate (APT) and tungsten powder. In recent years, the application research of sodium tungstate in biomedicine (such as insulin mimicking), environmental science (such as photocatalytic degradation of pollutants) and energy fields (such as sodium ion batteries) has grown rapidly. Technological progress and interdisciplinary integration have further expanded the application boundaries of sodium tungstate, making it the focus of modern materials science and green chemistry.
