Zirconium (IV) sulfate is an inorganic chemical compound from the group of sulfates .

Extraction and presentation

Zirconium (IV) sulfate tetrahydrate can be obtained by reacting zirconium oxychloride with sulfuric acid. If an SO ₃ content of 64% is exceeded, acidic sulfates such as Zr (SO ₄ ) ₂ · H ₂ SO ₄ · 2H ₂ O or Zr (SO ₄ ) ₂ · H ₂ SO ₄ · H ₂ O precipitate. The anhydrate is obtained by smoking the tetrahydrate or zirconium oxide chloride with concentrated sulfuric acid.

properties

Zirconium (IV) sulfate tetrahydrate has an orthorhombic crystal structure with the space group Fddd (space group no. 70) (a = 1162 pm , b = 2592 pm, c = 5532 pm). The anhydrate is a microcrystalline powder that is very hygroscopic. In air it initially forms an unstable solution from which the normal tetrahydrate crystallizes. When the tetrahydrate is heated to 100 ° C, water of crystallization is released and the trihydrate is formed, at 380 ° C the anhydrate is then formed. A 5- and 7-hydrate is also known.

use

Zirconium (IV) sulfate can be used as an intermediate in the purification of zirconium salts such as zirconium (IV) chloride by reprecipitation.
