Research in the field of nanoparticles has yielded a number of novel solutions in ceramics, cosmetics, biomedicine and electronics. Nanoparticles exhibit unexpected behavior when the atomic and molecular properties of the basic elements are altered. This article deals with the properties and applications of strontium iron oxide nanoparticles.
Strontium iron oxide (SrFe12O19) nanoparticles are oxide magnetic nanostructures that have a high surface area. They are also available in the form of nanofluids and nanodots. Strontium iron oxide particles are also known as strontium dodecairon nonadecaoxide and strontium ferrite. Strontium belongs to Block S, Period 5 and iron to Block D, Period 4 and oxygen to the Block P and Period 2 of the periodic table.
The chemical properties of strontium iron oxide are given in the table below.
