Useful:

• General Description: Tungstate, also known as tetraoxotungstate(2-) or tungstate ion (WO42-), is a key component in the synthesis of zirconium tungstate, as demonstrated in the thermal decomposition study of layered zirconium salts. The study highlights its role as a reagent (e.g., ammonium paratungstate) in forming crystalline zirconium tungstate, which undergoes thermal decomposition, suggesting its stability and reactivity in high-temperature processes.

Thermal decomposition of several layered zirconium salts

10.1023/A:1010136403670

The study investigates the thermal decomposition of zirconium molybdate, tungstate, and arsenate, focusing on their mass losses and thermal behavior. The chemicals used in the study include zirconium oxychloride, ammonium-heptamolybdate, hydrochloric acid, ammonium-paratungstate, arsenic acid, and conc. hydrochloric acid, which served as starting materials and reagents for the synthesis of the zirconium salts. The purpose of these chemicals was to prepare well-defined crystalline forms of the zirconium salts for thermal analysis, aiming to understand their thermal behavior and decomposition processes.
