Solubility of Magnesium in Molten Magnesium Chloride
TLDR
MgCl2 系に対するMgの溶解度はアルカリ塩化物の添加によって減少し, その依存性の勾配からMgの絷電力が750℃で測定された。Abstract:
溶融MgCl2 系に対する金属Mgの溶解度とMg濃淡電池の起電力が750℃で測定された。Mg濃淡電池の起電力はMgの濃度の対数に直線的に依存することがわかった。この依存性の勾配からMgの溶解生成物はMgoまたはMg22+であることが推定された。溶融MgCl2に対するMgの溶解度はアルカリ塩化物の添加によって減少し, その減少割合はアルカリ金属の原子番号の増加とともに増大することが認められた。アルカリ塩化物系ではその原子番号の増加とともにMgCl2との錯形成能が増大するので, Mgの溶解度は溶解塩中のMg2+ 活量に比例すると考えられる。したがって, 溶融塩中におけるMgの溶解種はMgoよりもむしろMg22+イオンであると結論されるであろう。read more

In-situ observation on the magnesiothermic reduction of TiCl4 around 800 °C by microfocus X-ray fluoroscopy
Akihiro Kishimoto,Tetsuya Uda +1 more
TL;DR: In this paper, in-situ observation on the magnesiothermic reduction of TiCl4 was performed by microfocus X-ray fluoroscopy, and the authors successfully observed that the molten magnesium creeps up on container walls rapidly and that porous titanium is mainly deposited and grows on the walls by reduction of gaseous TiCl 4 by the magnesium.
