Titanium(Ti) atomic and molecular weight, atomic number and elemental symbolTitanium is a Block D, Group 4, Period 4 element. The number of electrons in each of Titanium's shells is 2, 8, 10, 2 and its electron configuration is [Ar] 3d2 4s2. The titanium atom has a radius of 144.8.pm and its Van der Waals radius is 200.pm. Titanium Bohr ModelIn its elemental form, CAS 7440-32-6, titanium has a silvery grey-white appearance. Titanium's properties are chemically and physically similar to zirconium, both of which have the same number of valence electrons and are in the same group in the periodic table. Elemental Titanium Titanium has five naturally occurring isotopes: 46Ti through 50Ti, with 48Ti being the most abundant (73.8%). Titanium is found in igneous rocks and the sediments derived from them. Titanium was first discovered by William Gregor in 1791 and is named after the word Titanos which is Greek for Titans.

High Purity (99.999%) Titanium Oxide (TiO2) Powder In its metallic form, titanium is both strong and light weight, and it's highly resistant to corrosion. Thus it can be found in numerous aerospace and military applications. In its oxide form, it is used in low grades to produce a white pigment. High Purity (99.999%) Titanium (Ti) Sputtering TargetTitanium is the basis for numerous commercially essential compound groups, such as titanates for electronic and di-electric formulations and in crystal growth for ruby and sapphire lasers. Titanium is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity). Elemental or metallic forms include pellets, rod, wire and granules for evaporation source material purposes. Titanium nanoparticles and nanopowders provide ultra-high surface area which nanotechnology research and recent experiments demonstrate function to create new and unique properties and benefits. Oxides are available in powder and dense pellet form for such uses as optical coating and thin film applications. Oxides tend to be insoluble. Fluorides are another insoluble form for uses in which oxygen is undesirable such as metallurgy, chemical and physical vapor deposition and in some optical coatings. Titanium is also available in soluble forms including chlorides, nitrates and acetates. These compounds can be manufactured as solutions at specified stoichiometries.

Titanium metal is not considered to be toxic, although titanium in the form of metal shavings or powder is considered a fire hazard. Safety data for Titanium and its compounds can vary widely depending on the form. For potential hazard information, toxicity, and road, sea and air transportation limitations, such as DOT Hazard Class, DOT Number, EU Number, NFPA Health rating and RTECS Class, please see the specific material or compound referenced in the Products tab below.
