In this study crown magnesium produced from Turkish calcined dolomite by the Pigeon Process was refined and corrosion tests were applied.

By using factsage thermodynamic program metalothermic reduction behavior of magnesium oxide and silicate formation structure during this reaction were investigated. After thermodynamic studies were completed, calcination of dolomite and it's metalothermic reduction at temperatures of 1473 K, 1523 K and within a vacuum (varied from 20 to 200 Pa) and refining of crown magnesium was studied. Different flux compositions consisting of MgCl2, KCl, CaCl2, MgO, CaF2, NaCl, and SiO2 with and without B2O3 additions were selected for the refining process. These tests were carried out at 963 K for 15, 30 and 45 minutes setting time.

Considerable amount of iron was transferred into the sludge phase and its amount decreased from 0.08% to 0.027%. This refined magnesium was suitable for the production of various magnesium alloys. As a result of decreasing iron content, minimum corrosion rate of refined magnesium was obtained 2.35 g/m2/day. The results are compared with previous studies.
