Ferrite is manufactured by normal
ceramic route.This involves Raw material mix in required molar
ratios, calcination to get uniform physical properties, milling,
compacting to the required shape, sintering and finishing. Most
important factors affecting the final properties of ferrite are
its chemistry and process conditions and both of these jointly
control the microstructure formation, which has a major role on
the magnetic and mechanical properties of ferrite.
Raw Material
Select raw materials in
required purity and physical properties.
Weighing
In proportion to the mold
ratio to get the required chemistry.
Mixing
To achieve the uniformity to
effective chemical reaction.
Calcination
Adjust the furnace condition
to get the required ferrite formation.
Crushing
Crush the calcined material
to suit further milling.
Additives/Milling
Additives for modifying
magnatic properties and milling to get fine particle to
control shrinkage and microstructure.
Binder Addition
Binder in the required
amount to get sufficient mechanical strength to the
green body.
Granulation
For achieving free-flowing
powder, which can flow in to the die-cast easily.
Pressing
To get the required size and
shape. Size is adjusted according to the shrinkage of
powder.
Sintering
To achieve the required
magnetic, electrical and mechanical properties for the
ferrite component.
