Abstract

A series of glass samples was prepared from mixtures of Na2B4O7 and V2O5. Measurements were made for infrared absorption and optical absorption spectra as a function of V2O5 content up to 10 mol%. The addition of V2O5 did not introduce any new absorption band as compared with the infrared spectrum of pure sodium tetraborate glass. The addition of V2O5 shifted the optical absorption edges towards lower energies, and introduced a new absorption band as compared with the optical absorption of pure Na2B4O7 glass. Differential scanning calorimetry as a function of V2O5 content was also measured.
