Aluminum-vanadium system
The nature of the aluminum-vanadium system has been reported on the basis of thermal, microscopic, chemical and X-ray evidence. The system contains six different solid phases at ambient temperatures: the four intermediate phase being peritectic in nature. Phase properties are summarized in Table 1.
متن کاملVanadium(V) oxide arsenate(V), VOAsO4
The vanadyl arsenate, VOAsO(4), has been isolated by a solid-state reaction. The structure consists of distorted VO(6) octa-hedra and AsO(4) tetra-hedra sharing corners to build up VAsO(7) layers parallel to ac linked by edge-sharing of VO(6) octa-hedra, forming a three-dimensional framework.
متن کاملThe vanadium Magnéli phases V
To compare the metal-insulator transitions (MITs) of VO2 and V2O3 we analyze the relations between the structural and electronic properties of the vanadium Magnéli phases. These materials set up the homologous series VnO2n−1 (3 ≤ n ≤ 9) and have crystal structures comprising typical dioxide-like and sesquioxidelike regions. As the MITs of the vanadium Magnéli phases are accompanied by structura...
متن کاملDetermination of the Stability Constant of Vanadium (V) with Alaine
Formation equilibria of dioxy vanadium (V) complex with alanine in acidic media (pH<2.3) has been investigated potentiometrically and spectrophotometrically. In this condition the 1:1 complex has the formula VO2Y, where Y¯ represent the fully dissociated aminocarboxylate anion. The stability constant of VO2Y was determined as log KVO2Y=11.32±<e...
متن کاملAN AES INVESTIGATION OF ALUMINUM, Al OXIDE AND Al NITRIDE
The aluminum-L,,VV Auger spectra for elemental Al. Al oxide and Al nitride have been measured in an assessment of the utility of Auger spectroscopy in characterizing thin oxidized Al films used in model supported-metal catalyst studies. Clearly distinct spectra were found for the three surface chemical states. The oxide spectrum was shown to be similar to published spectra from bulk, single-cry...
