Zirconium (III) chloride is an inorganic chemical compound of zirconium from the group of chlorides .

Extraction and presentation

Zirconium (III) chloride can be obtained by reducing zirconium (IV) chloride with zirconium or aluminum .

{\ displaystyle \ mathrm {3 \ ZrCl_ {4} + Zr \ longrightarrow 4 \ ZrCl_ {3}}}

{\ displaystyle \ mathrm {3 \ ZrCl_ {4} + Al \ longrightarrow 3 \ ZrCl_ {3} + AlCl_ {3}}}

properties

Zirconium (III) chloride comes in two modifications. α-Zirconium (III) chloride is a blue-black crystal powder with a trigonal crystal structure isotype to that of α- titanium (III) chloride with the space group P 3 m 1 (space group no.164) , a = 5.961 Å , c = 9.669 Å. The β-modification is in the form of olive-green needles and has a hexagonal crystal structure with the space group P 6 ₃ / mcm (No. 193) , a = 6.382 Å, c = 6.135 Å. In air it oxidizes to ZrOCl ₂ .
