Abstract

This study aims to investigate the effect of different flux addition and time on refining of crown magnesium produced via Pidgeon Process. The different flux compositions (MgCl₂, KC1, CaCl₂, MgO, CaF ₂, NaCl, and SiO₂) with and without B₂O ₃ additions and reaction durations (15-45 min) were selected in order to lower the iron content in Mg ingot samples at 690 °C. The chemical composition of the final ingots was measured by using wet chemical analysis technique. Each final ingot was also subjected to a corrosion test to understand the influence of iron to Mg corrosion. It is found that selected flux compositions can decrease iron content in the Mg ingot from 0.080 % to 0.0027 %. The corrosion test results showed that corrosion rates decreased with decreasing iron content in Mg ingots. The minimum corrosion rate obtained was 0.235 mg/cm²/day.
