A new pyrophoric alloy

Abstract

The nanophasic cobalt ferrite was prepared by self-igniting solution combustion method. Mix up of fuel approach by fuel lean condition was employed for the combustion reaction to prepare the nanosized cobalt ferrite for the first time. Alanine and glycine were chosen as fuels for the combustion reaction. It was found that there was a remarkable changes in structural parameters and its magnetic behaviour of the as-prepared samples. XRD and Raman analysis were used to confirm the cubic spinel structure of the material. Rough surface morphology was turn up into porous type of morphology, when the alanine and glycine ratio of 30:20 used for the combustion reaction. TEM micrographs confirmed the particle size, shape and its lattice arrangements of the cobalt ferrite magnetic nanoparticles. The SAED pattern confirmed the crystalline nature of the as-prepared material. The saturation magnetization values were increased from 9 emu/g to 15 emu/g, when increasing the alanine and glycine ratio from 10:40 to 30:20 for the combustion reaction. It describes that the combination of alanine and glycine (30:20) was gained the maximum heat during the combustion reaction, so that these kind of results were obtained from the as-prepared condition.
