Zirconium IV Fluoride ZrF

Zirconium forms only one important oxide, zirconia Zr02, which is amphoteric in character. The normal zirconium salts, like ZrC, are readily hydrolysed in solution giving rise chiefly to zirconyl salts, containing the divalent radical ZrO. The zirconates, e.g. Na2Zr03, are best produced from Zr02 by fusion methods. Zirconium also readily forms complex ions like hexafluorozirconate(IV) [ZrF ] , produced by heating zirconia with potassium hydrogen fluoride.
