Preparation of tin tetraiodide

Preparation[ edit ] Silicon tetrachloride is prepared by the chlorination of various silicon compounds such as ferrosiliconsilicon carbideor mixtures of silicon dioxide and carbon. The ferrosilicon route is most common. Brine can be contaminated with silica when the production of chlorine is a byproduct of a metal refining process from metal chloride ore.

See Article History Titanium processing, the extraction of titanium from its ores and the preparation of titanium alloys or compounds for use in various products. Owing to the formation on its surface of an oxide film that is relatively inert chemically, it has excellent corrosion resistance in most natural environments.

In addition, it is light in weight, with a density 4. Because its atomic diameter is similar to many common metals such as aluminum, iron, tin, and vanadium, titanium can easily be alloyed to improve its properties.

Like iron, the metal can exist in two crystalline forms: This allotropic behaviour and the capacity to alloy with many elements result in titanium alloys that have a wide range of mechanical and corrosion-resistant properties.

Although titanium ores are abundant, the high reactivity of the metal with oxygen, nitrogen, and hydrogen in the air at elevated temperatures necessitates complicated and therefore costly production and fabrication processes.

History Titanium ore was first discovered in in Cornish beach sands by an English clergyman, William Gregor. The actual identification of the oxide was made a few years later by a German chemist, M. Klaproth gave the metal constituent of this oxide the name titanium, after the Titans, the giants of Greek mythology.

Pure metallic titanium was first produced in either or by M. Nevertheless, Hunter did indicate that the metal had some ductility, and his method of producing it by reacting titanium tetrachloride TiCl4 with sodium under vacuum was later commercialized and is now known as the Hunter process.

Metal of significant ductility was produced in by the Dutch scientists A. In William J. Kroll of Luxembourg produced significant quantities of ductile titanium by combining TiCl4 with calcium. By Kroll had produced 20 kilograms 50 pounds of titanium and was convinced that it possessed excellent corrosion and strength properties.

By this time, he had changed the reducing agent from calcium to magnesium metal. Kroll is now recognized as the father of the modern titanium industry, and the Kroll process is the basis for most current titanium production.

Air Force study conducted in concluded that titanium-based alloys were engineering materials of potentially great importance, since the emerging need for higher strength-to-weight ratios in jet aircraft structures and engines could not be satisfied efficiently by either steel or aluminum.

As a result, the Department of Defense provided production incentives to start the titanium industry in Similar industrial capacity was founded in Japan, the U. After this impetus was provided by the aerospace industrythe ready availability of the metal gave rise to opportunities for new applications in other markets, such as chemical processing, medicine, power generation, and waste treatment.

Ores Titanium is the fourth most abundant structural metal on Earthexceeded only by aluminum, iron, and magnesium. Shaub The predominate minerals are rutile, which is about 95 percent titanium dioxide TiO2and ilmenite FeTiO3which contains 50 to 65 percent TiO2.
