(2019) 26: 2185-2196 DOI: https://doi.org/10.1007/s11771-019-4165-9 Experimental study on repair characteristics of damaged rock salt of underground gas storage YIN... and Development Company, Daqing 163000, China Central South University Press and Springer-Verlag GmbH Germany, part of Springer Nature 2019 Abstract: Damage in rock salt has significant implication......
at 1000 ℃ in cryolite-alumina molten salt by means of cyclic voltammetry. The high current peak in a typical cyclic voltammogram was discussed. It is considered that a type of oxyfluoroaliminate complex... potential increases with alumina content increasing which indicates that the alumina content determines the anodic process in the cryolite-alumina molten salt system. Key words: anode behavior; aluminum......
Trans. Nonferrous Met. Soc. China 22(2012) 2320-2326 Corrosion resistance of 91W-6Ni-3Fe refractory metal, TiAl compound and iron based alloys in molten aluminum XIAO Hua-qiang, CHEN Wei-ping, LIU... investigated. Corrosion experiments or static immersion-tests were carried out in pure molten aluminum at 750 ℃. The surface micro-topographies, corrosion interfaces and phase compositions of the immersed......
. At present, the primary methods to prepare metal and its alloys include metal casting, thermic reduction method and molten salt electrolysis method [8]. However, the metal casting and thermic reduction process have many disadvantages, such as complicated production process, high-energy consumption, serious metal burning and inhomogeneous alloy composition. On the contrary, molten salt electrolysis......
