Box 6091, Damascus, Syria aut Phase relations in the Al2O3-MoO3 and Al-MoO3 systems, investigated by X-ray powder diffraction, FTIR, and DTA techniques [Elektronische Daten] [M. Kassem] This study focuses on the phase transformation induced during mixing fixed quantities of MoO3 and Al2O3 or aluminum powder (2, 3, 4, 5, 10, 20, 40, 50%). Different solid solutions were identified by x-ray powder diffraction, FTIR, and DTA. In the Al2O3 concentration range 2-20%, the only phase present besides MoO3 is Al2(MoO4)3. The concentration of this latter phase increases with increasing Al2O3 concentration, while the concentration of MoO3 decreases at the same time. For high concentrations of Al2O3 (more than 20%), MoO3 disappears completely, and Al2(MoO4)3 becomes the dominant phase. When MoO3 is mixed with various concentrations of aluminum powder, three kinds of samples were obtained. For aluminum concentration less than 4%, no other phase than MoO3 is present. For the concentration of aluminum in the range 4-20%, a new phase of Al2(MoO4)3 is observed. This phase increases while MoO3 decreases with increasing aluminum loading. At high concentrations of aluminum (more than 20%), the MoO3 disappears completely, and a new phase M0.975Al0.025O2 is present besides the Al2(MoO4)3 already formed.
