Titanium - Wikipedia
Titanium readily reacts with oxygen at 1,200 °C (2,190 °F) in air, and at 610 °C (1,130 °F) in pure oxygen, forming titanium dioxide. Titanium is one of the few elements that burns in pure nitrogen gas, reacting at 800 °C (1,470 °F) to form titanium nitride, which causes embrittlement.

titanium processing, the extraction of titanium from its ores and the preparation of titanium alloys or compounds for use in various products. Titanium (Ti) is a soft, ductile, silvery gray metal with a melting point of 1,675 °C (3,047 °F). Owing to the formation on its surface of an oxide film that is relatively inert chemically, it has excellent corrosion resistance in most natural ...
Smelting Technology of Metal Titanium and Titanium Alloy ...
In the industrial production of titainum and titanium alloys, the most commonly used techniques are vacuum arc remelting (VAR) and cold hearth melting. Vacuum Arc Remelting VAR technology can refine the ingot structure in titanium alloy smelting and improve the purity of the product. The main developments of this technology in recent years are as follows: Fully …
What Are The Titanium Smelting Technologies - industry ...
Sponge titanium is melted into a liquid in an electric furnace before it can be cast into a titanium ingot. Since the reaction needs to be carried out at a high temperature, it can be seen that the titanium material requires a lot of energy during the production process, which is why the titanium material is expensive.

Extraction and refining TiCl 4. The production of titanium metal accounts for only 5 percent of annual titanium mineral consumption; the rest goes to the titanium pigment industry. Pigments are produced using either a sulfate process or a more environmentally acceptable carbo-chlorination process (described below) that converts TiO 2 into TiCl 4.The latter process also …
Titanium - Wikipedia
Titanium is a chemical element with the symbol Ti and atomic number 22. It is a lustrous transition metal with a silver color, low density, and high strength, resistant to corrosion in sea water, aqua regia, and chlorine.. Titanium was discovered in Cornwall, Great Britain, by William Gregor in 1791 and was named by Martin Heinrich Klaproth after the Titans of Greek mythology.
