and for catalyst in
the chemical
industry.

ceramics and
essential element
for human because
it helps us to use
glucose and also
added to steel to
produce stainless
steel.

It’s metal produced
and solid as grey
powder and used in
alloys, catalysts,
electrodes. Also used
in valves and boiler
plates.

/ W
Is used for the
filaments of light
bulbs. It is alloyed
with other metals to
strenghten them,
example: military
armour and cutting
tools.
VANADIUM
/ V
Is used in alloy, steel
and coloured
television screens.

9. COMMON ELEMENTS AND THEIR USES
NIOBIUM
/ Nb
Resists corrosion due
to an oxide film and
added in small
amounts to improve
stainless steels and
also used in plating
and coins.
TANTALUM
/ Ta
Is very resistant to
corrosion and so
finds use in
equipment for
handling corrosive
materials and used in
making medical skull
plates.
TITANIUM
/ Ti
Is used to make
lightweight alloys in
replacement of hip
joints and chemical
plants.

10. COMMON ELEMENTS AND THEIR USES

Is used in nuclear
reactors, briccks,
ceramics and
abrasives. Scissors
and knives can be
made from it.
HAFNIUM
/ Hf
Alloys are used to
make control rods for
nuclear reactors
because it will absorb
neutrons and has a
very high melting
point.

/ Y
Is used in television
screen to produce the
colour red and also in
radar technology. It is
employed in
superconductors,
metal oxides that
conduct electricity
without any loss of
