Figure 3From: Structural characterization and colour of MgxCu3-xV2O8 (0 ≤ x ≤ 3) and MgyCu2-yV2O7 (0 ≤ y ≤ 2) compositions An example of the diffraction profile refinement. The diffraction profile refinement by Rietveld’s method from Mg0.25Cu1.75V2O7 composition fired at 600°C. Crystalline phases: α-Cu2V2O7 (C1) and β- Cu2V2O7 (C2).Back to article page
