FUN FACTS

In the 1950’s and 1960’s, the Soviet Union pioneered the use of titanium in military and submarine applications (Alfa Class and Mike Class) as part of programs related to the Cold War.

Titanium is also just as strong as steel but weighs 45% less. Titanium is twice as strong as aluminum but weighs 60% more.

Current Event

Boeing, a US aircraft manufacturer, and Rostech, a Russian Technology, are working on an agreement to obtain more titanium and use it in aircraft produce more aircraft. This will help Boeing produce more 737s. Boeing will also help Rostech build the aerospace industry. They also are supporting a titanium innovation center to produce better titanium alloys.

Purification of titanium

http://www.platts.com/RSSFeedDetailedNews/RSSFeed/Metals/8865062

1. Titanium ore (Titanium dioxide) is heated with carbon and chlorine to produce titanium tetrachloride.

2. Then the titanium tetrachloride is mixed with magnesium or sodium in an atmosphere of argon gas. The magnesium or sodium displaces the titanium on the chloride and the result is purified titanium plus either magnesium chloride or sodium chloride.

Where it is Abundant

Apollo 17 brought back moon rocks with 12.1% titanium dioxide

Where it's most abundant

It is found in the ground as ore.

Also found as titanium dioxide or iron titanium dioxide

Australia

Canada

India

China

South Africa

Russia

It is the 9th most abundant element in the earth's crust.

Some is found in coal ash, plants, and the human body.

Cost of Titanium

Origin of Titanium

the value of pure titanium is $661/100g

The world demand for titanium ore has been in balance with the supply: about 5 million tons per year.

Characteristic Properties

In 1791,William Gregor discovered it at Cornwall, Great Britain, by Martin Heinrich Klaproth named after the Titans in Greek mythology.

Chemical Properties

Titanium

1. Excellent resistance to corrosion. It can resist dilute sulfuric or hydrochloric acids. It is soluble in concentrated acids.

2. The surface of titanium medal oxidizes immediately when exposed to air. Titanium reacts with oxygen at 1200 C in air and 610 C in pure oxygen to form titanium dioxide.

3. When exposed to nitrogen, titanium metal becomes coated with titanium nitride.

4. Titanium metal cannot melt in open air because it burns before it reaches the melting point. It can melt in a vacuum.
