The Kroll process is a method used to extract titanium from its ores. It involves reducing titanium tetrachloride (TiCl4) with magnesium in a high-temperature environment. This process is significant because it allows for the production of high-purity titanium, which is essential for various applications, including aerospace and medical devices. Developed by William Kroll in the 1940s, the Kroll process has become the primary technique for titanium production. It is favored for its efficiency and ability to produce titanium with minimal impurities. The process has contributed to the growth of the titanium industry, making it a vital material in modern technology.
