TITANIUM

Titanium has a low density, good strength, and has a good corrosion resistance. The metal burns in air and it is the only element that burns in nitrogen. * Group in periodic table: 4 * Group name: Transition Metals * Period in periodic table: 4 * Atomic Number: 22 * Melting Point: 1668 °C

To extract Titanium we use the Kroll process. Titanium ore is called rutile. Rutile contains titanium dioxide - TiO2.
Titanium dioxide is converted into titanium chloride - TiCl4.
We cannot use electrolysis because titanium chloride is covalent which means that it does not conduct electricity.

We use Titanium for many different things such as: * Body piecing * Ring * Hip Replacement * Spork * Bicycle frame

The Kroll process: It begins by passing chlorine gas through rutile in a chlorinator. Throughout the first stage of the process, titanium tetrachloride and chlorides are produced from the ore. Oxygen is removed from the titanium tetrachloride through distillation and this leaves the titanium tetrachloride in a liquid form. We add liquid magnesium or sodium to the titanium tetrachloride, and the end result is a metallic sponge.
This titanium sponge is crushed and then put into a electrode vacuum furnace. The sponge melts inside the furnace but, unlike other metals, it is not poured because it becomes a solid in the vacuum. A titanium slab produced during the Kroll process can weigh 5,000 kilograms The multiple steps of the Kroll process mean that titanium is much more expensive to produce than similar types of metal, such as steel.

What Titanium is also used for? * Titanium alloys

Essay about Pure Titanium

Titanium is defined as a light, very strong metal that can resist very high temperatures. Titanium’s atomic number is 22 and its atomic weight is 47.867. Titanium comes from the Greek word titans, which means “first sons of the Earth.” In 1791 William Greger was the person who discovered titanium, but in 1910 Matthew Hunter was the person to discover pure titanium. Titanium is as strong as steel and twice as strong as aluminum. It is 45% lighter than steel and only 60% heavier than aluminum. Titanium…
