Abstract

Soft ferrites are magnetic materials with a spinel structure that have prominent properties such as high electrical resistance, low hysteresis losses, and high permeability, making them suitable for use in catalysts. In this study, ternary CuNiF and CoMnF ferrite nanoparticles were synthesized by sol-gel autocombustion method using glycine, urea and citric acid as fuels. Moreover, ammonium perchlorate (AP) nanoparticles were prepared by adding dissolved ammonium perchlorate to Hydroxyl-terminated polybutadiene (HTPB), homogenization and solvent distillation. Then, the powder nanomaterials were characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM), techniques. The average particle size of CuNiF and CoMnF ferrite nanoparticles and ammonium perchlorate nanoparticles were calculated 22.15, 34.12 and 68.2 nm, respectively. The catalytic effect of the synthesized ferrite nanoparticles on the thermal decomposition of nano-AP was investigated by TGA and DTG methods. Also, activation energy was calculated using DSC with three different heating rates by Kissinger equation.
