Abstract

Purpose. Study of the main characteristics of synthesizing processes of magnetite and iron nanopowders by hydrogen reduction from hydroxide compound (α-FeOOH). Materials and methods. α-FeOOH hydroxide nanopowder was obtained by chemical precipitation from aqueous solutions of iron (III) nitrate Fe(NO3)3 (10 wt. %) and alkali NaOH (10 wt. %) at room temperature, pH = 11, under the condition of continuous stirring. Synthesizing processes of Fe3O4 and Fe nanopowders by hydrogen reduction of hydroxide α-FeOOH were carried out in a tubular furnace "SNOL 0.2/1250". The study of the crystal structure as well as the composition of the powder samples was performed by X-ray phase analysis. The size and morphology of nanopowder particles were investigated by scanning and transmission electron microscopes. The specific surface area of the powders was measured by using BET method by low-temperature nitrogen adsorption. The average size of the powders articles was determined via the measured value of specific surface area. Results. It has been established that the optimal temperatures corresponding to the values of the maximum specific rate for carrying out the synthesizing processes of Fe3O4 and Fe nanopowders by hydrogen reduction are 340 and 500 °C, respectively. The resulting products are nanopowders of pure Fe3O4 and Fe after being through hydrogen reduction process for 2 hours. It was shown that Fe3O4 nanoparticles consist of particles with indefinite shape, which are prone to the formation of flakes. They have a nanometer size (about tens of nm) and are in a sintered state with connections to several neighboring particles by isthmuses. Fe nanoparticles are mainly rounded and spherical, up to one hundred nm in size and distributed separately. Originality. For the first time, the optimal temperatures have been established for synthesizing processes of Fe3O4 and Fe nanopowders by hydrogen reduction from hydroxide compound. Practical value. The research results will serve as a basis for the synthesis of nanopowders based on Fe3O4 and Fe, guarantee the acceleration of processes, ensure the necessary properties of nanopowders and can be used for various fields of science, technology, ecology and oth.
