It is a blue-black solid that is highly sensitive to air. ==Preparation== The material was first claimed by Ruff and Wallstein who reduced zirconium tetrachloride with aluminium to give impure samples. Subsequently, the problem with aluminium contamination was solved when it was prepared by reduction using zirconium metal: :Zr + 3 ZrCl4 → 4 ZrCl3 When aluminium is used as the reducing agent with zirconium tetrachloride, a series of choloroaluminates are formed, for example () and Zr(AlCl4)3. Since the trihalides, such as zirconium trichloride, are comparatively nonvolatile, contamination can be avoided by using a gaseous reductant. For example, zirconium trichloride can be prepared by reduction of zirconium tetrachloride with hydrogen. :ZrCl4 + ½ H2 → ZrCl3 + HCl 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Zirconium(III) chloride」の詳細全文を読む スポンサード リンク
