Abstract

©Sociedad Mexicana de Ciencia y Tecnología de Superficies y Materiales. Wollastonite from Encarnaci & #243;n Villa Ju & #225;rez deposit located in Hidalgo, Mexico was used as raw material to fabricate glass using V2O5as former oxide. Powder fusion at 1350 & #176;C was carried out for glass fabrication. The obtained glasses were of amber, gray and black color; the most transparent glasses are those with a composition of 60 to 65[%] wt. of V2O5and 40 to 35 [%] wt. of wollastonite. XRD patterns of the samples show the presence of wollastonite-2M and the VO2orthorhombic crystalline phase. FT-IR and Raman spectroscopies revealed the formation of metavanadates and pirovanadates groups. In addition, drop of phase separation caused by liquid-liquid immiscibility was observed by scanning electron microscopy imaging. XPS analysis was carried out to analyze vanadium oxidation state and bonding and non-bonding oxygen estimation. The curve fitting of the high resolution spectra of the V 2p3/2peak showed the presence of V4+and V5+vanadium oxidation states for all glasses.
