説明
<p>In a molten zinc bath in a continuous galvanizing line, top dross particles crystallize as Fe2Al5 intermetallic compound containing Zn, which causes the surface defect of the final products by easily adhering to steel sheets. The present study focused on the analysis of crystal structure of the top dross by simultaneously exploiting first principle calculation and synchrotron X-ray diffraction of top dross prepared in a laboratory. The following results were obtained: The first principle calculation on top dross suggested that two Al atoms in the partially occupied four Al sites of Fe2Al5 based on the crystal structure proposed by Mihalkovič et al. were replaced by two Zn atoms. In addition, Al atoms in the two kinds of partially occupied Al sites in Fe2Al5 proposed by Burkhardt et al. was equally replaced by Zn atoms. The propose crystal structure of top dross was verified by the X-ray diffraction profile analysis using RIETAN-FP simulation as well as the experimentally determined lattice constant of Zn containing top dross.</p>
