Transcripts

so here we have a sample of titanium

wire titanium is a really quite

fantastic metal it's very very

lightweight and very very strong it's

used in construction materials very low

concentrations and as additives for

Alloys titanium is a very interesting

element and it's interesting because

it's very abundant on the planet it's

not the most abundant metal but it's

still pretty abundant this is a periodic

table where the area

of each of the elements

here represents the relative amount of

this material that is found on the earth

as you can see there's a lot of oxygen a

lot of carbon quite a lot of

boron Debb's favorite element some

aluminium again a lot and here titanium

is quite a reasonable amount nearly as

much as potassium so it's a very common

element so going to open it now and

we'll hopefully see the titanium wire

around the spindle so you can see it's a

really quite beautiful dark

coloration you can find large deposits

of titanium dioxide in various places

across the world we've just had a

visitor from South Africa who said not

far from where he works in East London

along the coast their large deposits of

titanium dioxide the problem is that it

is really quite hard to make titanium

metal out of the oxide because titanium

atoms bond strongly to the oxygen and

it's difficult to get them apart and get

the

metal and the reason why people want to

get the metal is because it's very light

here I've got a piece of titanium and

it's quite light you can see I can shake

it around in my hands without behaving

as as if it was a really heavy bar often

used as well in the construction of

aerospatial sort of capsules and

components to go into space because it's

light and strong being light by itself

is not much

use sodium is light the great thing

about titanium is that it is light and

it's strong and also it doesn't react

with water you couldn't make a car out

of sodium the first rainstorm and boom

but titanium is light it is strong so if

you're making a vehicle out of it the

vehicle isn't very heavy so you don't

need nearly as much fuel than if you're

making the vehicle out of steel usually

people make the vehicle out of aluminium

which is lighter than steel but is not

nearly as strong and the great thing

about titanium is it's fantastically

strong once you get the metal so the

problem getting the metal is from

titanium dioxide titanium dioxide is a

white powder in fact you can see it

around you if you look around the room

you're in almost certainly the walls are

white with titanium dioxide it's a very

cheap white pigment normally what

happens in the process for making

titanium metal is that first of all it

is converted to Titanium tetrachloride

TI

cl4 and if you just leave it as titanium

tetrachloride in the air it will react

with the air with water in the air and

go back to titanium dioxide you haven't

achieved anything in fact one of my

colleagues Rich

born showed Brady earlier what happens

with this reaction I've never seen it

but I had to stay in my office and work

however you can take titanium

tetrachloride and convert it to the

metal and once you've got the metal it's

pretty unreactive

provided that you keep it cold if you

put titanium at high temperatures in

oxygen it will burn so there are some

processes where you would like to use

the strength of titanium but because

there's oxygen there it's not

safe but cars and most airlanes don't

get hot enough for the burning in oxygen

to be a problem so it is a fantastic

material and if we could solve the pro

problem of how to make titanium metal

cheaply in terms of the energy needed to

convert the oxide into the metal then we

could have cars that were far more fuele

efficient and cheaper to run so it's a

really good goal tianium is used at the

moment in applications where strength

and lightness is more important than

cost if you're building fighter

aircraft where of course cost is

important you but you need it to be

pretty light or you can't can't get to

the speeds that you need to shoot down

the enemy and so on then they will use

titanium Alloys if those are

best you often use titanium for very

high pressure

applications when chemists want to do

experiments at high pressure they will

often use titanium

because again it is very light and again

strong it is also has a great advantage

that it's

non-magnetic and when you want to for

example do experiments in a high

magnetic field when you need something

strong you can't use steel because your

apparatus will be pulled away by the

magnet and nothing will work so titanium

has a very

special applications which can be very

useful but they could be so much more

useful if we could apply it more widely

it's used where you really need strength

and where money is not terribly

important is in hip implants in your hip

you want to have something that's very

strong and very light each time you move

your leg you don't want to be moving a

cannonball or something really heavy but

you want it to be really strong

and so again very often hip implants

will be made out of titanium the piece

that goes into your leg is made out of

titanium and ends in a ball and the part

that goes into your pelvis is often made

of polythene plastic so that you get the

ball and socket effect well one of the

most interesting applications of

titanium is as a catalyst for making

polythene

polyethylene the material material that

is used particularly for plastic

buckets and other plastic

objects and ethylene was first

polymerized turned into plastic some

people call it ethine rather ethylene

was turned into plastic before the

second world war with a very high press

reaction that produced a material that

was rather soft and you couldn't for

example use for making buckets and then

in the 1950s

um a German chemist called Zigler he

discovered partly also working with

Italian chemist called NATA that if you

take a titanium compound and an

aluminium compound together this was a

really good Catalyst and by really good

I mean one gram of this Catalyst could

produce a ton of

plastic so that because titanium is

relatively cheap it means you don't even

have to get the Catalyst out of the

plastic because there's so little of it

in the plastic you can just afford to

sell it when your plastic bucket without

losing much money does that mean there's

probably a little bit of titanium in my

plastic bucket at home

yes and there's probably more titanium

from the fact that you cleaned your

paintbrush when you were painting your

kitchen or bedroom with white paint so

there's titanium
