| appearance and properties | zirconium tetrachloride, alias Zirconium chloride, appearance and properties are white, shiny crystals or powders. Zirconium tetrachloride, a zirconium compound, is a precursor of many zirconium salts. |
| Structure | is different from titanium tetrachloride, in the solid ZrCl4, there is an octahedral coordination structure with a chlorine bridge connected to the zirconium atom. This explains the large differences in their melting points. This structure is also present in hfcl4. When the treatment is carried out using a Lewis base, the chlorine bridge in the Zr-Cl-Zr form is broken, thereby decomposing the polymer. For example, zirconium tetrachloride can undergo a chlorine displacement reaction with a hydroxyl-containing ligand, and can react with water to produce zrocl2. |
| Use | zirconium tetrachloride is a weak Lewis acid, it can form adducts ZrCl4 · PCl5 and ZrCl4 · 2 PCl5 with phosphorus pentachloride, or form hexachlorozirconate with alkali metal or alkaline earth metal chlorides. In addition, it can also take part instead of aluminum trichloride in the Friedel-Crafts reaction and the Diels-Alder reaction. zirconium tetrachloride is the most important precursor for chemical vapor deposition of zirconium dioxide and zirconium diboride. It is also used as a textile waterproofing agent, leather tanning agent, analytical reagent. used in the preparation of metal zirconium, pigment, textile waterproofing agent, leather tanning agent, etc. used in the preparation of metal zirconium, pigment, textile waterproofing agent, leather tanning agent, etc. for the preparation of zirconium compounds and organometallic organic compounds, can be used as solvent and remelting magnesium purification agent, with the effect of removing iron and silicon. used in the preparation of metal zirconium, pigments, textile waterproofing agents, leather tanning agents and Analytical reagents. |
| preparation | zirconium tetrachloride can be prepared by reacting chlorine with zirconium carbide (or a mixture of zirconium dioxide and carbon), then purified by sublimation method. |
| production method | zirconium dioxide and calcined carbon black are weighed according to the stoichiometric molar ratio, mixed evenly and then put into a porcelain boat. The porcelain boat was placed in a porcelain tube and calcined by heating to 500 °c in a stream of chlorine gas. The product was collected using a trap at room temperature. Considering the sublimation of zirconium tetrachloride at 331 ° C., it can be re-sublimated in a 300-350 ° C. Tube in a hydrogen stream to remove oxides and ferric trichloride from Zirconium chloride. |
