“…The micrographs of master alloys, obtained by using liquid aluminum cathode also presented for comparison. 7 It can be seen that the size and shapes of intermetallic compounds in master alloys are slightly different, but generally the structures of master alloys are similar. In the case of a tungsten cathode using, Al-W compounds presented in the master alloy can be eliminated by using an aluminum-wetted cathode (f.e.…”

“…1,2 This demand is conditioned by fact that small additions of different elements such as silicon, scandium, zirconium and boron significantly modify the structure and technological properties of aluminum. [3][4][5][6][7] Today the world market of aluminum alloys and master alloys is represented by several manufacturers (ALEASTUR, Spain; AMG Aluminum, USA-Canada; Ganzhou Wanfeng Advanced Materials Technology Co., Ltd., China and others).…”

A review of the existing methods for producing aluminum master alloys with silicon, zirconium, scandium and boron are given. Basic parameters, advantages and disadvantages of the existing methods are analyzed, indicating the need to develop new more energy-efficient technologies. The prospects of obtaining aluminum master alloys in the electrolysis of melts based on the KF-NaF-AlF 3 -Al 2 O 3 -MeO (MeO = SiO 2, ZrO 2 , Sc 2 O 3 , and B 2 O 3 ) system are considered. For this purpose, the results of physical and chemical measurements in these melts are presented, including data on the solubility of Al 2 O 3 , SiO 2, ZrO 2 , Sc 2 O 3 , and B 2 O 3 oxides in KF-NaF-AlF 3 melts, data on the effect of oxide additives on the liquidus temperature of studied melts, as well as data on the kinetics of electrowinning of aluminum and alloying element from KF-AlF 3 -Al 2 O 3 -MeO melts. Based on the measurements, the parameters were selected and electrolysis tests were carried out for obtaining aluminum master alloys with silicon, zirconium, scandium, and boron from its oxides. The composition and structure of the obtained master alloys were studied.

“…In recent years, the combination of mineral processing and hydrometallurgical separation technology has been widely used in the field of comprehensive recovery and extraction of scandium, which greatly improves the concentration ratio and recovery rate of scandium. In future research and production, the recovery metal and Al-Sc alloy [19][20][21][22]. To date, the key point of preparing ScCl 3 is how to reduce the hydrolysis rate of scandium chloride in ScCl 3 .…”

In this study, a one-step rapid heating novel process was used to prepare high-purity anhydrous scandium chloride molten salt with low-purity scandium oxide. High-purity anhydrous ScCl3 molten salt was used as the Sc-bearing raw material for preparing the Sc-bearing master alloy. Inert gas was used to enhance the purity of anhydrous scandium chloride and reduce the hydrolysis rate of scandium. The results show that high-purity scandium chloride (purity, 99.69%) with the scandium content of 29.61%, was obtained, and the hydrolysis rate of scandium was 1.19% under the conditions used: removing ammonium chloride; residual crystal water temperature of 400 °C; m(Sc2O3):m(NH4Cl) = 1:2.5; holding-time of 90 min; heating-rate of 12 °C/min; and argon flow of 7.5 L/min. XRD, SEM, and EPMA analyses further verified that anhydrous scandium chloride crystallization condition was relatively good and the purity of high-purity anhydrous scandium chloride approached the theory purity of anhydrous scandium chloride.
