General Description

Tungstate refers to any compound containing the tungstate ion (WO42-). Tungstate compounds are often used as catalysts in various chemical reactions, as well as in the production of a wide range of materials, such as ceramics, pigments, and coatings. Sodium tungstate, in particular, is used in the manufacturing of tungsten metal and various tungsten-related chemicals. Tungstate-based materials are also employed in the production of phosphors for fluorescent lighting and in the formulation of corrosion-resistant coatings. Additionally, tungstate compounds have been studied for their potential use in energy storage and conversion applications, such as in the development of rechargeable batteries and solar cells.

Chemical behavior of tungstate solutions. Part 1. A spectroscopic survey of the species involved

This study is focused on the composition and the evolution of tungstate ions solutions as a function of pH and increasing concentrations. The Raman analysis showed that, during the titration of the tungstate solutions, WO 42-, HWO4- ions and probably W 2O72-, HW2O72- and H2W2O7 solvated species could exist in aqueous solutions. For diluted solutions, additions of a strong acid does not cause any precipitation, whereas the formation of the unstable solid tungstic acid (H2WO4 or WO3·H2O) could occur in concentrated solutions.
