Uses
Zirconium dichloride oxide is utilized as a precursor to prepare other zirconium compounds. It is employed in acid dyes, pigment toners and antiperspirants. It finds application as a rubber additive and a fiber treatment agent. It is also used in paint drying, refractories, ceramics and glaze.
Purification Methods
Recrystallise the chloride several times from water [Ferragina et al. J Chem Soc, Dalton Trans 265 1986]. Recrystallisation from 8M HCl gives the octahydrate as white needles on concentrating. It is also formed by hydrolysing ZrCl4 with water. After one recrystallisation from H2O, 99+% grade zirconyl chloride had Ag, Al, As, Cd, Cu, Hf, Mg, Na, Sc and V at 20, 1.8, 0.6, 0.6, 0.4, 8.4, 0.4, 2.4, 80 and 3 ppm, respectively. (See above.)
