Titanium

Question 1

physical properties of titanium ?

Answer 1

it is light
can maintain its strength at high temperatures
is highly resistant to corosion
- bio compatible (can enter into the body without rejection
- low density

Question 2

what are some uses of titanium

Answer 2

• nuclear reactor engines
• exhaust parts for high performance cars
• pipes
• body replacement e.g. hip replacement

Question 3

why is extracting titanium using carbon ineffective

Answer 3

it forms brittle carbides which make the metal too brittle for use

Question 4

How would you extract Titanium ?

Answer 4

heat rutile to 1000degrees with chlorine and carbon to get brid of oxygen
TiO2 + 2Cl2 + 2C > TiCl4 + 2CO2

mix TiCl4 with magnesium and heat up to 9000degrees in an helium-argon atmosphere to prevent Titanium from reaction with Oxygen
TiCl4 + 2Mg > Ti + 2MgCl2

-TiCl4 is 99.9% pure and can be used as a catalyst
- TiCl4 can be reacted with Mg to produce pure Titanium for engines, bike frames etc.
- you can ereact TiCl4 with Oxygen to form TiO which is used in paint
