RT Journal Article SR Electronic A1 Fedorovich Chervonyj, Ivan A1 Olexandrovich Listopad, Dmytro T1 Thermodynamic Laws of Impurities in the Titanium Sponge Inflow during its Production JF Acta Mechanica Slovaca YR 2009 VO 13 IS 4 SP 40 OP 47 DO 10.2478/v10147-010-0035-z UL https://www.actamechanica.sk/artkey/ams-200904-0005.php AB There are the key rules discussed of spongy titanium production process by Magnesium thermal reduction of Titanium tetrachloride. Thermodynamic analysis carried out of the possible effects of interaction of alloying elements (Molybdenum, Tungsten, Niobium, Tantalum, Zirconium), as well as interaction reactions of the main components (Iron, Chromium, Manganese, Nickel) with Titanium chlorides and with oxygen, as for Magnesium thermal method of Titanium obtaining.
