Nanotechnology and nanoparticle research have opened doors to novel and innovative solutions that have not been explored before. The principle upon which this technology is built is the altering of the atomic and molecular states of elements in order to bring out properties that are not exhibited by elements in their original states.
Yttrium iron oxide (Y3Fe5O12) nanopowder are available in ultra high purity passivated form, dispersed, nanofluidic, nanowhiskers and nanocomposits. This material finds applications in manufacture of fuel layer cells, bio nano materials, bio sensors, textiles etc. Yttrium belongs to Block D, Period 5 and Iron to Block D, Period 4 and oxygen to the Block P and 2nd Period in the periodic table. Some of the other names by which this powder is known are yttrium ferrite garnet, Iron yttrium oxide and yttrium iron garnet (YIG).
