Discovery date Discovered by William Gregor Origin of the name The name is derived from the Titans, the sons of the Earth goddess of Greek mythology.

Glossary Group A vertical column in the periodic table. Fact box. Glossary Image explanation Murray Robertson is the artist behind the images which make up Visual Elements. Appearance The description of the element in its natural form. Biological role The role of the element in humans, animals and plants. Natural abundance Where the element is most commonly found in nature, and how it is sourced commercially.

Uses and properties. Image explanation. The symbol is representative of the Titans of Greek mythology, after which the element is named.

It is based on early votive offering figurines. Titanium is as strong as steel but much less dense. It is therefore important as an alloying agent with many metals including aluminium, molybdenum and iron. These alloys are mainly used in aircraft, spacecraft and missiles because of their low density and ability to withstand extremes of temperature. They are also used in golf clubs, laptops, bicycles and crutches.

Power plant condensers use titanium pipes because of their resistance to corrosion. Because titanium has excellent resistance to corrosion in seawater, it is used in desalination plants and to protect the hulls of ships, submarines and other structures exposed to seawater.

Titanium metal connects well with bone, so it has found surgical applications such as in joint replacements especially hip joints and tooth implants. The largest use of titanium is in the form of titanium IV oxide. It is a bright white pigment with excellent covering power. It is also a good reflector of infrared radiation and so is used in solar observatories where heat causes poor visibility. Titanium IV oxide is used in sunscreens because it prevents UV light from reaching the skin.

Nanoparticles of titanium IV oxide appear invisible when applied to the skin. Biological role. Titanium has no known biological role. It is non-toxic. Fine titanium dioxide dust is a suspected carcinogen. Natural abundance. Titanium is the ninth most abundant element on Earth. It is almost always present in igneous rocks and the sediments derived from them. It occurs in the minerals ilmenite, rutile and sphene and is present in titanates and many iron ores.

Titanium is produced commercially by reducing titanium IV chloride with magnesium. Help text not available for this section currently. Elements and Periodic Table History. The first titanium mineral, a black sand called menachanite, was discovered in in Cornwall by the Reverend William Gregor.

He analysed it and deduced it was made up of the oxides of iron and an unknown metal, and reported it as such to the Royal Geological Society of Cornwall. This is a form of rutile TiO 2 and Klaproth realised it was the oxide of a previously unknown element which he named titanium.

It was not until that M. Hunter, working for General Electric in the USA, made pure titanium metal by heating titanium tetrachloride and sodium metal. Atomic data.

Listen to Titanium Podcast Transcript :. You're listening to Chemistry in its element brought to you by Chemistry World , the magazine of the Royal Society of Chemistry. This week, you may be surprised to learn just how reliant you are on this widely used element that cleans and protects our environment.

It is notoriously hard to make, but we have come to rely on it and indeed we couldn't do without this element or its compounds today. So, why is it so important? We actually use 4 million tons of TiO2 each year, a lot of it for paint and other applications that need something that is bright white, insoluble and not toxic, like medicines and toothpaste.

In the food industry it is additive number E, used to whiten things like confectionary, cheeses, icings and toppings. It is also used in sunscreens, since it is a very opaque white and also very good at absorbing UV light. The ability to absorb UV light helps the TiO2 to act as a photocatalyst. This means that when UV light falls upon it, it generates free electrons that react with molecules on the surface, forming very reactive organic free radicals. Now you don't want these radicals on your skin, so the TiO2 used in sunscreens is coated with a protective layer of silica or alumina.

In other situations, these radicals can be a good thing, as they can kill bacteria. Scientists have found that if you introduce small amounts of different elements like nitrogen or silver into the TiO2, UV light is not needed as visible light will do the same job. You can put very thin coatings of TiO2 onto glass or other substances like tiles ; these are being tested in hospitals, as a way of reducing infections.

When water gets onto this type of glass, it spreads out, so that it doesn't fog up think car wing mirrors and also washes away dirt. This is the basis of Pilkington's ActivT self-cleaning glass, a great British invention. Scientists are now investigating building TiO2 into the surfaces of buildings, pavements and roads, with the aim of getting rid of chewing gum and even dog mess.

The natural forms that are less frequently found in nature are the anatasite and the brooquite. Both the pure rutile and the pure anatasite are white. The black basic oxide, FeTiO 3 , is found in the natural form as the natural mineral called ilmenite; this is the main commercial source of titanium. There is no known biological role for titanium.

There is a detectable amount of titanium in the human body and it has been estimated that we take in about 0. It is not a poison metal and the human body can tolerate titanium in large dose. Elemental titanium and titanium dioxide is of a low order of toxicity.

Laboratory animals rats exposed to titanium dioxide via inhalation have developed small-localized areas of dark-colored dust deposits in the lungs. Excessive exposure in humans may result in slight changes in the lungs.

Effects of overexposure to titanium powder: Dust inhalation may cause tightness and pain in chest, coughing, and difficulty in breathing. Contact with skin or eyes may cause irritation. Routes of entry: Inhalation, skin contact, eye contact. Low toxicity. When in a metallic powdered form, titanium metal poses a significant fire hazard and, when heated in air, an explosion hazard.

Home Periodic table Elements Titanium. Over the last 50 years the element titanium has been steadily gaining in importance. The major interests range from titanium metal, which combines good resistance to corrosion with high strength and low specific gravity, to the white pigment, titanium dioxide, and titanium tetrachloride, a chemical intermediate.

This paper reviews the manufacture of these materials and particularly deals with the properties and applications of titanium dioxide, which, by reason of its high refractive index, possesses outstanding lightening and hiding power, making it the first choice among white pigments.
