SrFe12O19 hexaferrite particles were synthesized by a chemical co-precipitation technique with a precipitator NH3·H2O. To improve the wear resistance property of a material, another set of SrFe12O19 hexaferrites was synthesized containing non-ionic surfactant polyoxyethelene (20) sorbitan monolate (Tween-80). The prepared Sr-M hexaferrite precipita...

The M-type Strontium Hexaferrite SrFe12O19 particles were prepared by a Self propagating High temperature Synthesis (SHS) route. Precursors were heated under two different conditions: microwave heating for 30 minutes and sintered at 950°C for 4 hrs. The dielectric properties: dielectric constant (ε'), dielectric loss (tan δ) and ac conductivity (σa...

Nano oxide materials are polycrystalline in nature with crystallite size from 1-100 nm. These materials exhibit a variety of properties (magnetic, electrical, mechanical and optical) that are different but improved with comparison of coarse powders. Zinc substituted manganese spinal ferrite powders (Mn 1-x Zn x Fe 2 O 4 with x= 0.5) were prepared u...
