Titanium

Macro Mondays: The Periodic Table

Titanium is a chemical element with symbol Ti and atomic number 22. It is a lustrous transition metal with a silver colour, low density and high strength. It is highly resistant to corrosion in sea water, aqua regia, and chlorine.

 

Titanium was discovered in Cornwall, Great Britain, by William Gregor in 1791 and named by Martin Heinrich Klaproth for the Titans of Greek mythology.

The element occurs within a number of mineral deposits, principally rutile and ilmenite, which are widely distributed in the Earth's crust and lithosphere, and it is found in almost all living things, rocks, water bodies, and soils.

 

The metal is extracted from its principal mineral ores by the Kroll and Hunter processes.

 

The most common compound, titanium dioxide, is a popular photocatalyst and is used in the manufacture of white pigments. Other compounds include titanium tetrachloride (TiCl4), a component of smoke screens and catalysts; and titanium trichloride (TiCl3), which is used as a catalyst in the production of polypropylene.

 

This example is my titanium Breitling watch.

This watch has had nearly 15 years of continuous wear - even titanium is showing the signs when seen at macro.
