Titanium is an element (symbol Ti) like gold, silver and platinum. It’s atomic number is 22, with atomic weight of 47.9, an electron configuration of 2-8-10-2, and a specific gravity of 4.5. Titanium has a melting point of 3020 F (1660C) and a boiling point of 5949 F (3287C). It is a silvery white non ferrous metal with the highest strength to weight ratio of any known element. For this reason titanium is the favored material in the aerospace industry. 85% of the structural components in the Space Shuttle are made of titanium.

Titanium is a strong, light metal. It is as strong as steel and twice as strong as aluminum, but is 45% lighter than steel and only 60% heavier than aluminum. Titanium is not easily corroded by sea water and is used in propeller shafts, rigging and other parts of boats that are exposed to sea water. Titanium and titanium alloys are used in airplanes, missiles and rockets where strength, low weight and resistance to high temperatures are important. Since titanium does not react within the human body, it is used to create artificial hips, pins for setting bones and for other biological implants. Unfortunately, the high cost of titanium has limited its widespread use.

With the LaCie DL DVD+/-RW drive and Toast 6 Titanium, Macintosh video professionals will have the power and flexibility to create full-length productions without using complicated and expensive DLT (digital linear tape). Additionally, all users will benefit from the ability to back up personal DVDs without having to first compress the dual layer into a single layer, a step which requires additional software and sacrifices video and audio quality.

Titanium has potential use in desalination plants for converting sea water into fresh water. The metal has excellent resistance to sea water and is used for propeller shafts, rigging, and other parts of ships exposed to salt water. A titanium anode coated with platinum has been used to provide cathodic protection from corrosion by salt water.

Titanium is readily available from commercial sources so preparation in the laboratory is not normally required. In industry, reduction of ores with carbon is not a useful option as intractable carbides are produced. The Kroll method is used on large scales and involves the action of chlorine and carbon upon ilmenite (TiFeO3) or rutile (TiO2). The resultant titanium tetrachloride, TiCl4, is separated from the iron trichloride, FeCl3, by fractional distillation. Finally TiCl4 is reduced to metallic titanium by reduction with magnesium, Mg. Air is excluded so as to prevent contamination of the product with oxygen or nitrogen.
