Samples Containing Zirconium or Hafnium | Inorganic Ventures

Zirconium tetrachloride is not as reactive as the TiCl 4 where hydrolysis results in the formation of derivatives such as the oxychloride, ZrOCl 2, instead of the oxide as is the case with TiCl 4. Materials containing Zirconium and Hafnium compounds are also relatively non-hazardous and do not present unique sampling and handling problems.

Zirconium - Wikipedia

Zirconium is a chemical element with symbol Zr and atomic number 40. The name zirconium is taken from the name of the mineral zircon (the word is related to Persian zargun (zircon;zar-gun, "gold-like" or "as gold")), the most important source of zirconium. It is a lustrous, grey-white, strong transition metal that closely resembles hafnium and, to a lesser extent, titanium.
