Zirconium iodide, in comparison with similar zirconium containing minerals, has an increased deformability and plasticity, which is preserved even at very low temperatures. Iodide zirconium is very resistant to concentrated inorganic acids. Among the disadvantages, it should be noted insufficient mechanical strength and corrosion resistance, especially at low temperatures.
To obtain the substance under consideration, the iodination method is used, since zirconium binds well to halogens, forming chemically stable compounds. With thermal distillation, the inevitable impurities are removed, and a substance of high chemical purity is obtained. Zirconium iodide is produced in the form of bars, which are used in the production of scavengers for atomic particles and individual parts of vacuum devices. Since the material is very sensitive to storage conditions, it is packaged in special sealed containers.
Zirconium iodide is also used as a getter for arc furnaces in which rare metals and alloys are smelted. Due to the reduced content of harmful impurities, zirconium can be machined mechanically, obtaining products of different configurations. After shaping the zirconium iodide rods are surface cleaned and ground.
To buy rods from iodide of zirconium, issued according to technical norms and requirements of TU 95.46−82, the company Electrovek-steel offers. Products are sold at economically favorable prices from the manufacturer. The supplier ensures the timely delivery of products to any point specified by the customer.
The method of purification of zirconium, including the production of gaseous metal compounds with iodine (iodides) and their subsequent decomposition into pure metal and iodine. The first reference to the iodide method appeared in 1923 when it was used by the Dutch scientist Van Arkel to produce pure tungsten. A high-yield process produces pure metals with a total impurity content of up to 6… 10% (titanium, zirconium).
Cleaning is carried out in hermetically sealed containers, within which «low» (400−700 ° C) and «high» (1300 ° -1700 ° C) temperature zones are created. Raw metal in the form of powder, chips, or individual blanks is mixed with a small amount of iodine in the low-temperature zone. The resulting vapor of zirconium iodide decomposes into iodine and free metal when it passes into the high-temperature zone. Subsequently, iodine undergoes reverse diffusion into the parent metal, again forming iodide,
While the zirconium vapor is deposited in a dense layer on the heated filament of the heated element (the yarn is usually made of the same pure metal). All impurities that do not form iodides are isolated by iodide refining. In this way, pure metal rods with a diameter of up to 0.04 m and a length of up to 1 m are obtained.
The iodide process is expensive and not very productive, and is gradually replaced by more promising methods (for example, zone melting). However, the purest metals are still produced by the iodide process.
