Abstract: The standardless simultaneous equation method with regression analysis of multi specimens in quantitative phase determination of XRD was applied for sur- face dispersion studies on V_2O_5-TiO_2 system. The dispersive characteristics of vana- dium oxide in V_2O_5-TiO_2 mixtures and in V_2O_5/TiO_2 catalysts prepared from oxyvanadium oxalate after roasting were compared in this paper.
