The Kroll process is a pyrometallurgical industrial method for producing metallic titanium by reducing titanium tetrachloride with liquid magnesium at 800 to 850 degrees Celsius inside a stainless steel retort. The Luxembourg-based metallurgist William Justin Kroll developed the process after experimenting with several reducing agents, achieving his major breakthrough using magnesium at around 1000 degrees Celsius in a molybdenum-clad reactor, and he later extended the same method to zirconium production while working at the Albany Research Center in the United States. Since 2001 the Kroll process has been the dominant method of commercial titanium production worldwide, having replaced the earlier Hunter process, and it remains a major driver of global magnesium production as well.
