It is well known that the chemical potential of ions dispersed in a solvent is inversely proportional to the dielectric constant of the medium . This relationship directly affects the solubility of the precursors or intermediate compounds during chemical synthesis. To improve the solubility of synthetic compounds, mineralising agents are commonly added to the system. These agents form soluble mobile complexes that allow for the presence of ions with the necessary valence for the reaction , . In turn, the increase in the thermal stability of the reagents affects the mass transfer and solubility. Consequently, it alters the kinetics of the reactions involved and helps stabilise the denser structures .
