Abstract

We synthesized various types of Barium and strontium hexaferrite nanoparticles using Barium chloride and strontium nitrate salts by co-precipitation method in microwave. The solvent was either water, ethylene glycol or mixture of them with three different natural surfactants. XRD and SEM analysis were performed to evaluate the morphological characters of the products. The mean diameter of Barium and strontium hexaferrite particles in all products was less than 100 nm, indicating successful formation of nanoparticles. The purity of nanoparticles was documented by FT-IR spectrometry. SEM analysis shows that the Nanostructures of products would change with respect to type of solvents and surfactants. So it is possible to change the size and structure of nanoparticles for various purposes with manipulation of primary parameters. In the second phase various proportions of Barium chloride and strontium nitrate were used for production of nanoproducts. All the products had pure nanoparticles of Barium and strontium hexaferrite which again was confirmed by XRD analysis. VSM analysis was performed to study the ferromagnetic characteristics of the products. Hysteresis curves disclosed that all the products have ferroMagnetic properties. strontium hexaferrite nanoparticles are hard ferromagnetics and Barium hexaferrite nanoparticles are soft ferromagnetics and nanocomposite Barium/strontium hexaferrite nanoparticles have the intermediate ferroMagnetic properties.
