The powder was found to consist of ZnMn2O4, MnO, ZnO, and carbon by XRD analysis. After the reaction between pellets of the powder and the alloy in liquid at 973 K or 1073 K for 3.6×103 s, Mg content in the alloy decreased from 4.0 to 2.3 mass%. And at the same time, contents of Mn and Zn in the alloy increased from 0 to about 0.2 and 0.1 mass%, respectively. During the reaction, metallic Mg in the liquid Al-Mg alloy was found to move in to the pellets to form MgO. It may be assumed that an exchange reaction between Zn2+ at ZnO in the pellets and Mg2+ from the liquid alloy takes place.日本金属学会Journal Articleapplication/pdfhttp://hdl.handle.net/2115/74946https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/74946/1/DiovNT.pdf0021-48761880-6880AN00062446日本金属学会誌73107737772009-10jpninfo:doi/10.2320/jinstmet.73.773publisher
