Zirconium selenate

Zirconium selenate is an inorganic compound with the chemical formula Zr(SeO4)2. Its tetrahydrate can be obtained by the reaction of selenic acid and a saturated aqueous solution of zirconium oxychloride octahydrate (or zirconium hydroxide ). The tetrahydrate belongs to the orthorhombic crystal system and is isostructural with Zr(SO4)2·4H2O. It loses water when heated and becomes anhydrous at 220-230 °C. It reacts with potassium fluoride to obtain K2Zr(SeO4)2F2·3H2O.
