What is the Kroll process?
The Kroll process is a method used to convert ore into titanium metal. Engineers, manufacturing companies and medical companies use titanium for different purposes because it is as strong as steel, but is lighter. Titane traces can be found in minerals such as Rutile and Ilmenite, but the pyrometallurgical process Kroll removes dirt and produces metal that can be used in medical implants, construction and design of aircraft. A German scientist named Martin Heinrich Klaproth named him after the same year after the Greek God Titan. Scientists have begun to develop ways to extract the newly discovered element from Rutile and Ilmenite, and in 1910 a chemist named Matthew Hunter developed a method for the production of titanium metal by mixing rutile with coke and chlorine. The Hunter process has become the first process of industrial scale for the production of this metal.
In the 30th year, Scientist from Luxembourg called William Kroll began experimenting with Titan. In 1938 he developed what later became known as the Kroll method. Kroll after the outbreak of the second withThe sentence wars moved to the United States and its process of titanium metal production was patented in the United States in 1940. The patent was later abolished by the Federal Government because Kroll was not a citizen of the United States. He entered the seven -year -old legal battle, which culminated in the renewal of the patent.
The Kroll process begins with the passage of the chlorine gas rutile in the chlorinator. During the first phase of the process, titanium tetrachloride and chlorides are made from ore. Oxygen is removed from the titanium tetracholdire through the distillation process, leaving the tetrachloride titanium in liquid form. Scientists add a liquid magnesium or sodium to the tetrachloride titanium by an aconneous result is a metal sponge.
This titanium sponge is crushed and then inserted into a consumer electrode vacuum furnace. The fungus melts inside the furnace, but unlike other metals, it does not depend on the vacuum. Titanium ingot produceAry during the Kroll process can weigh in excess of 5,000 kilograms (5.51 tonnes). More steps of the Kroll process means that titanium is much more expensive than similar types of metal, such as steel.
After the development of the Kroll process, William Kroll used a similar technique to create zirconium metal. Both Titan and Zirconium are now used to produce parts for space containers. Titanium, unlike Zirconia, is not a health risk and is therefore also used for medical implants.
