Hunter process Wikipedia

The Hunter process was the first industrial process to produce pure ductile metallic titanium.It was invented in 1910 by Matthew A. Hunter, a chemist born in New Zealand who worked in the United States. The process involves reducing titanium tetrachloride (TiCl 4) with sodium (Na) in a batch reactor with an inert atmosphere at a temperature of 1,000°C. . Dilute hydrochloric acid is then used

titanium processing Technology, Methods, & Facts

Nevertheless, Hunter did indicate that the metal had some ductility, and his method of producing it by reacting titanium tetrachloride (TiCl 4) with sodium under vacuum was later commercialized and is now known as the Hunter process. Metal of significant ductility was produced in 1925 by the Dutch scientists A.E. van Arkel and J.H. de Boer, who

Hunter Process an overview ScienceDirect Topics

Porous titanium has been known since 1910 as a titanium sponge produced in the Hunter process (invented in 1910). However, it was only after World War II that titanium foam gained industrial significance as a result of the development of commercial production of titanium sponge using the Kroll process (in 1948).

Other articles where Hunter process is discussed: titanium processing: History: is now known as the Hunter process. Metal of significant ductility was produced in 1925 by the Dutch scientists A.E. van Arkel and J.H. de Boer, who dissociated titanium tetraiodide on a hot filament in an evacuated glass bulb.

What Is the Hunter Process? (with picture)

Sep 17, 2020· The Hunter process is a metallurgy process used to purify titanium; it was very successful until the 1940s, when the process lost its popularity to the less expensive Kroll process.To start the Hunter process, coke, titanium dioxide and chlorine must be collected and heated. After this, sodium is added and the mixture is heated again. When the sodium and titanium are heated

The History of Titanium Titanium Processing Center

May 06, 2016· Hunter’s process was the reason the metal was able to be extracted from the ore, however it only worked on a small scale. Dr. Willheim Kroll later created a process that reduced the titanium effectively, so that it could be used in large manufacturing efforts. Instead of using sodium to reduce the metal he used magnesium.

makes this process worth investigating. Titanium powder The Armstrong process (developed by Interna-tional Titanium Powder, Chicago, Ill.) can be looked upon as a modification of the Hunter method in which titanium powder is made in a continuous process, rather than the batch method. The Arm-strong process produces titanium by the reduction of

Matthew Hunter Wikipedia

Matthew Albert Hunter (1878-1961) was a metallurgist and inventor of the Hunter process for producing titanium metal.. Hunter was born in Auckland, New Zealand in 1878 and received his early education in local public schools. He completed his Secondary education at Auckland Grammar School.He attended Auckland University College, where he earned his Bachelor's in 1900, and his Master's degree

Titanium Types of Corrosion

Feb 11, 2002· Many process streams, particularly H 2 SO 4 and HCl solutions, contain enough impurities in the form of ferric, cupric ions, etc., to passivate titanium and give trouble-free service. In some cases, it may be possible to inhibit corrosion by the addition of suitable passivating agents.

How titanium production really happens

How titanium production really happens. Titanium production began more than two centuries ago, when scientists first synthesized raw ore into shiny, lustrous metal. In 1910, titanium tetrachloride was reacted with molten sodium to prepare the first pure titanium metal for the world, by the Hunter process.

History Production of Titanium

Pure metallic titanium was first produced by M.A Hunter, in 1910, in New York. He achieved this by reducing titanium tetrachloride with sodium in an airtight steel vacuum. This method of producing pure titanium is now known as the Hunter process. (1) Balanced equation of the Hunter Process: TiCl4 + 4 Na --> 4 NaCl + Ti

Timeline of titanium Timelines

Aug 22, 2019· Titanium is first obtained as pure metal at the beginning of the century. The Hunter process becomes the first industrial process to produce pure ductile metallic titanium. 1930–1950 : The only methods allowing the processing of titanium into useful shapes are the powder metallurgy techniques applied to fines of titanium sponge.

Titanium Properties and Characteristics

Oct 31, 2019· The use of titanium metal, in any form, only really developed after World War II. In fact, titanium was not isolated as a metal until the American chemist Matthew Hunter produced it by reducing titanium tetrachloride (TiCl 4) with sodium in 1910; a method now known as the Hunter process.

History Developments and Applications Titanium

Hunter’s process involved mixing TiO2 with coke and chlorine. By applying heat to the titanium dioxide, it would produce TiCl4, which could be reduced with sodium to create an alloying agent that would, for another few decades, mostly be used as an alloying agent in steel.
