Preparation of Zirconium Compounds
Zirconium is a highly reactive metal that forms stable compounds with a variety of other elements. These compounds can be prepared through a number of different chemical reactions, depending on the desired end goal. In this article, we will discuss the preparation of three specific zirconium compounds – zirconium oxide, zirconia, and zirconyl chloride.
Zirconium Oxide
Zirconium oxide is a white powder that can be synthesized from zirconium metal. This process begins with the reduction of pure zirconium metal to an oxide. This can be achieved by the addition of oxygen gas to a heated crucible of the metal. This reaction produces zirconium monoxide, which is then further reduced to zirconium dioxide by the addition of more oxygen gas. This process can be carried out at temperatures of 1600°C.
Zirconia
Zirconia, or zirconium dioxide, is a white powder produced by the thermal decomposition of zirconium salts. This process involves the heating of the zirconium salts to temperatures above 700°C, resulting in the conversion of the zirconium salt into zirconium dioxide. This white powder is then cooled and collected.
Zirconyl Chloride
Zirconyl chloride is a white powder that is prepared via the chlorination of zirconium hydroxide. This process begins with the preparation of the zirconium hydroxide, which is done by reacting pure zirconium metal with hydrochloric acid. This produces a solution of the zirconium hydroxide. Then, this solution is mixed with chlorine gas and heated to 95-120°C. This reaction produces zirconyl chloride, which is then separated from the other reaction products and cooled.
Conclusion
In conclusion, zirconium compounds can be prepared through a variety of chemical reactions. Zirconium oxide, zirconia, and zirconyl chloride can all be prepared through the use of different processes that involve the manipulation of various reactants and temperatures. Through these processes, these compounds can be made and used in various applications.
