A LUMINIUM
D ESCRIPTION

Its a chemical element in the boron group
Its symbol: Al
Its atomic number:油13
Its a silvery white, soft, ductile metal.
Instead, its found combined in over 270 different minerals
The chief ore of aluminium is bauxite
H ISTORY

A LUMINIUM

Ancient Greeks and Romans used aluminium salts as:
 dyeing mordants
 astringents for dressing wounds
The metal was first produced in 1825
¬Discovered by H. C. Oersted

P ROPERTIES

It is a very abundant element in the nature
It is a light metal under point of merger
His color is white and reflects well the electromagnetic
radiation
Good electrical and thermal driver
U SES

A LUMINIUM

The uses that aluminium gives to nowadays are
MULTIPLE and we can divide them by sectors:
Electricity and communication
Transport
Building and construction
Packings

R ECYCLING

It takes between 200 and 500 years to deteriorate
Any product of aluminium can be recycled infinite times
without losing his properties
the material can be re-used
H ISTORY

T ITANIUM

Titanium was discovered included in a minera Great
Britain by William Gregor
He found black sand by a stream
He noticed the sand was attracted by a magnet

D ESCRIPTION

It is a metal of transition
It has a silver greyish color
It forms alloys with other elements to
improve the mechanical presentations
It has a small thermal and electrical
conductivity
T ITANIUM
P ROPERTIES

Titanium is not free in the nature
It has a density of 4507 kg/m3
Point of merger of 1675 属C
It is paramagnetic
Lighter than steel
T ITANIUM
U SES

The two most useful properties of the metal are corrosion
resistance and the highest strength-to-density.
Metallic alloys
Aeronautical and aerospace industry
In surgery
Heat interchangers in the desalination plants
In metallurgy

R ECYCLING

The special steels can be recycled in junk yards or
authorized residues managers
B IOCHIPS

Theyre essentially miniaturized laboratories
They can perform simultaneous biochemical reactions
Biochips enable researchers to :
 screen large numbers of biological analytest
 detection of bioterrorism agents.

B IOSENSORS

Its an analytical device
It combines a biological component with a physicochemical
component
It consists of three parts:
 The biological sensor
 The transducer
 The detector
