Effect of heat treatment on preparation and structural properties of nanocrystalline strontium hexaferrite

摘要

Magnetocrystalline strontium hexaferrite nanoparticles have been synthesized by sol gel technique. The structural behavior of calcinated particles have been analyzed with the help of X-ray diffraction technique. X-ray pattern confirms the formation of hexaphase at 900°C for 5 hours with sharp and intense diffraction peaks. The calcinations process seems to be more favorable for the formation of magnetic particles for the application of high density recording media. Mid-IR characteristic absorption frequency confirms the lattice vibration of metal-oxygen bonds at octahedral and tetrahedral sites.
