Abstract

<span style="font-size:11.0pt;line-height:115%; font-family:" calibri","sans-serif";mso-ascii-theme-font:minor-latin;mso-fareast-font-family:="" "times="" new="" roman";mso-fareast-theme-font:minor-fareast;mso-hansi-theme-font:="" minor-latin;mso-bidi-font-family:arial;mso-ansi-language:en-us;mso-fareast-language:="" en-us;mso-bidi-language:ar-sa"="">The thermal conductivity of V₂O₅-P₂O₅ glass system has been experimentally determined in the temperature range 303-422 K. The data covered the glass composition range from 60 to 80 mol% of V₂O₅. It has been observed that the thermal conductivity increases linearly with temperature. The results obtained confirmed that the major contribution to the thermal conductivity of this glass system is due to lattice vibrations. The values of density, molar volume, lattice thermal conductivity (λ_L) band gap energy, melting temperature, electronic (λ_e) and bipolar component of thermal conductivity (λ_bp) are also reported.</span>
