Vanadium-bearing phases in crystallized ferroalloy slags
European Journal of Mineralogy (February 1995) 7 (1): 183-186


Phase compositions and microstructures of slags obtained during the production of ferrovanadium and ferromolybdenumvanadium alloys have been studied, by optical microscopy, SEM, XRD and EPMA techniques. A series of simple and complex oxides, calcium aluminates and silicates were identified, including a new phase SVCA (complex calcium vanadium oxide-silicate) with the composition Ca (sub 4) Al (sub 15.14) V (sub 5.15) Mg (sub 1.0) Fe (sub 0.026) Ti (sub 0.3) Mn (sub 0.024) Si (sub 2.36) O (sub 40) , space group P<$E 1 back 40 up 40 ->; a 10.273, b 10.634, c 8.808 Aa, alpha 106.24, beta 95.71, Gamma 124.47 degrees ; Z = 4. The structure is of aenigmatite type.
