Encyclopedia > Hunter process

The Hunter process was the first industrial process to produce pure ductile metallic titanium, and was invented in 1910 by M. A. Hunter, an American chemist. General Name, Symbol, Number titanium, Ti, 22 Chemical series transition metals Group, Period, Block 4, 4, d Appearance silvery metallic Atomic mass 47. ... -1...


In the process rutile (a mineral consisting of titanium dioxide, TiO2) is mixed with chlorine and coke and then extreme heat is applied, which produces titanium tetrachloride (TiCl4). The titanium tetrachloride is reduced with sodium to form titanium. This process successfully produces very high quality titanium, however it was replaced in all but the most demanding applications by the more economical Kroll process in the 1940s. Rutile in trellis texture characteristic of secondary rutile. ... Titanium dioxide, also known as titanium(IV) oxide or titania, is the naturally occurring oxide of titanium, chemical formula TiO2. ...

Coke is a solid carbonaceous residue derived from low-ash, low-sulfur bituminous coal. ... Titanium tetrachloride (TiCl4) is used for commercial production of pure titanium metal. ... General Name, Symbol, Number sodium, Na, 11 Chemical series alkali metals Group, Period, Block 1, 3, s Appearance silvery white Atomic mass 22. ... The Kroll process is a pyrometallurgical industrial process used produce metallic titanium and was invented in 1940 by William J. Kroll, at the Albany Research center in Oregon. ...

Industrial process - Wikipedia, the free encyclopedia (902 words)
Industrial processes are procedures involving chemical or mechanical steps to aid in the manufacture of an item or items, usually carried out on a large scale.
Most of the processes are complex and require large capital investments in machinery, or a substantial amount of raw materials, in comparision to batch or craft processes.
Temperatures of 1300 K were produced around the 8th century by blowing air through the heated mixture in a bloomery or blast furnace (12th century); producing a strong but brittle cast iron.
Kroll process - Wikipedia, the free encyclopedia (412 words)
The Kroll process is a pyrometallurgical industrial process used to produce metallic titanium and was invented in 1940 by William J. Kroll, at the Albany Research center in Oregon.
The Kroll process has not been replaced by a molten electrolytic process because of redox recycling, diaphragm failure and dendritic deposition in the electrolyte solution.
However another process, the FFC Cambridge Process, has been patented for a solid electrolytic solution, and there is a partial process for eliminating the titanium-sponge processing.
