Zirconia: Synthesis and Characterization | IntechOpen

The most common route is to precipitate zirconium oxychloride crystals (ZOC), with subsequent purification from all contaminants (crystal route). Less known is the process (liquid route) that involves the direct precipitation of zirconium basic sulfate (ZBS). This route will yield a less pure product, with contaminants such as silica and titanium.

Novel reusable sulfate-type zirconium alginate ion-exchanger …

The binding energy of AHB@Zr-SO 42− during F − removal process was −3.80 eV, it was more negative than the binding energy value of AHB@Zr, which meant a more thermodynamically feasible process (Fig. S10 in Supporting information). Therefore, F − was easier to exchange with SO 42− on AHB@Zr-SO 42− than AHB@Zr.
