Zircon is one of the most chemical stable compounds (Δ G 1400 K ° = 1489.1 kJ / mol) [2]. This is due to the high coordination of bisdisphenoid ZrO 8 in a tetragonal structure with SiO 4 tetrahedra [3]. Therefore, mineral acid other than HF cannot attack zircon and very aggressive reaction conditions are require to breakdown the strong binding between zirconium …
