Titanium:

Question 1

What are some properties of titanium?

Answer 1

= resistant to corrosion

Question 2

How do we extract titanium?

Answer 2

= titanium ore contains TiO2
= carbon cannot be used as a reducing agent because Tic is brittle
= mg is used as the reducing agent
=

Question 3

How many stages does this take place with?

Answer 3

= 2 stages- batch process
= only small amounts are made at one time
= expensive

Question 4

What happens in stage 1 ?

Answer 4

= TiO2 is converted to ticl using chlorine and carbon
= purified by fractional distillation in argon atmosphere

Question 5

What happens in stage 2?

Answer 5

= ticl is reduced using magnesium to form titanium and mg chloride

Question 6

What kind of conditions is stage 2 carried out in?

Answer 6

= argon atmosphere
= prevents the titanium formed from reacting with water or oxygen

Question 7

Why is titanium expensive?

Answer 7

= expensive cost of mg
= batch process- slower process,
= argon atmosphere to remove the oxygen
= high temperatures are required
