The aim of this study is to create a physicochemical analysis of the formation conditions of synthetic zinc selenite, ZnSeO3 · 2H2O and an experimental investigation of its thermal stability, dehydration, and dissociation. This study has been carried out using a comprehensive thermal analysis (thermogravimetry and differential scanning calorimetry) within the temperature interval from 25–600°C. It has been established that ZnSeO3 · 2H2O dehydrates at 81–222°C through four stages corresponding to the formation of intermediate hydrate species: ZnSeO3 · 5/3H2O, ZnSeO3 · H2O, and ZnSeO3 · 1/3H2O.
