Phase relations in the aluminothermic reduction of ZrO2

Study of Controlled Aluminum-Vanadium Alloy Prepared by Vacuum Resistance Furnace

“…The traditional production methods of Al-V alloy are the self-propagating method and two-step method [12][13][14][15]. In the self-propagating method, V 2 O 5 and Al are used as raw materials, CaF 2 or CaO is selected as a slag-forming agent, and Mg or KClO 3 is used as an igniter to obtain V-Al alloy with different V contents.…”

Synthesis of Aluminum-Matrix Alloys with Al-Zr-W by Metallothermy of Oxides

“…The processes of direct components alloying, reduction of metals from salts during electrolysis and aluminothermic reduction of oxides are used in synthesis technologies of aluminum alloys and ligatures containing rare metals [6][7][8][9][10][11]. The use of metallothermal processes for the production of multicomponent alloys by means of joint reduction of the initial mixture of the oxides or individual thermodynamically stable metal oxides is economically rather expedient [12][13][14][15][16][17][18]. The goal of this research work is to obtain aluminum alloy with a high content of zirconium and tungsten by the metallothermal method and to investigate it.…”

Synthesis of Al-Zr Master Alloys via the Electrolysis of KF-NaF-AlF3-ZrO2Melts

“…9 Methods for the aluminothermic synthesis of Al-Zr master alloys from ZrO 2 in molten KCl-NaF-AlF 3 and CaF 2 -CaO mixtures at the temperatures of 850-1150 and 1600-1650 • C, respectively, are described in the literature. [10][11][12] However, the described methods have disadvantages such as a low zirconium conversion rate (30-85%) into the master alloy, the necessity of periodical substitution of molten mixtures and separation of alloys, as well as the resulting solid-liquid slag.…”
