Lead haxaferrite (PbFe12O19) nanoparticles have been developed by a new way preparing using the sol gel auto combustion route, without adding external surfactant. The present work focused on the synthesis and characterization of PbFe12O19 nanoparticles at low temperature using cherry juice as a novel fuel and green capping agent for the first time. The effect of optimum amount of reductant, calcination temperature on the morphology and size of products were investigated. The size and agglomeration of the nanoparticles increase with decreasing cherry juice content. When the amount of cherry juice is 20 mL and calcination temperature is 800 degrees C, the product is pure and found to be PbFe12O19 nanoparticles. The products were characterized by X-ray diffraction pattern (XRD), scanning electron microscope (SEM), transmission electron microscopy (TEM), energy dispersive spectrometry (EDS). Furthermore, vibrating sample magnetometer (VSM) was used to study the magnetic properties of PbFe12O19 samples. (C) 2016 The Society of Powder Technology Japan.
