Ferro Fluids Market

applications, as they have both magnetic and liquid properties. Ferro fluids can be employed in making of optical
modulators, tunable optical fiber filter, magneto-optical wavelength filter, nonlinear optical materials, optical
grating, optical switches, and hyperthermia. Presently, ferro fluids are utilized in making sealing agents. Ferro fluids
could form leak free liquid seals, which can offer long-term stability in pump applications, CVD equipments, etching
system, epitaxial growth system, robots, x-ray generator, gas induction mechanism, vacuum chunk mechanism,
arch discharger, vacuum furnace, and ion implanter.
The basic sealing components consist of a permanent magnet, ferro fluid, two magnetic pole pieces, and a
magnetically permeable shaft. The pole pieces combined with the magnetic structure and the rotating shaft helps in
concentrating the magnetic flux in between the radial gap under each pole. Ferro fluid is applied to the radial gap,
which produces a hermetic seal between them. Ferro fluids are also utilized globally for biological applications.
Biological molecules coated with magnetic nanoparticles can be controlled externally with the help of
electromagnetic frequencies. Magnetic field is intrinsically penetrable into human tissue, which can be utilized into
the immobilization or transport of magnetically tagged biological entities and magnetic nanoparticles. Currently,
ferro fluids are being utilized to make high performance loudspeakers, as they can dampen the movement of the
cone passively as well as remove heat from the voice coil. Additionally, ferro fluids are employed as a material for
nondestructive testing of other components such as stainless steels, magnetic tapes, and turbine blades
The recent rise in demand for high quality electronics, sealants, non-destructive medical equipment, and expansion
in research & development sector is driving the expansion of the ferro fluid market globally. Consumer electronic is a
rapidly expanding segment of the market. The global consumer base for sealants, electronics, and medical sectors is
likely to extend further in the next few years due to increased demand in major economies such as India, China, the
U.S., Germany, and France. This, in turn, is anticipated to boost the need for ferro fluids. Major restraints for the ferro
fluids market are the high capital required for equipment manufacturing and limited technological applications.
