Phase formation in the system involving silver, magnesium, and indium molybdates

The subsolidus region of the Ag2MoO4-MgMoO 4-In2(MoO4)3 ternary salt system has been studied by X-ray powder diffraction. The formation of new compounds Ag1 - x Mg1 - x In1 + x (MoO4) 3 (0 ≤ x ≤ 0.6) and AgMg3In(MoO4) 5 has been established. The unit cell parameters of solid-solution samples have been determined. The Ag1 - x Mg1 - x In 1 + x (MoO4)3 phase of variable composition has a NASICON-type structure (space group R ?3c) AgMg3In(MoO 4)5 is isostructural to sodium magnesium indium molybdate of the same formula unit and crystallizes in triclinic system (space group P ?1, Z = 2) with the following unit cell parameters: a = 7.0374(5) ?, b = 17.932(1) ?, c = 6.9822(4) ?, α = 87.309(6)°, β = 100.832(6)°, γ = 92.358(6)°. The compounds Ag1 - x Mg1 - x In1 + x (MoO4)3 and AgMg3In(MoO4)5 are thermally stable up to 960 and 1030°C, respectively.

Thermal and X-ray diffraction studies of the solid-solid interactions in CuO-MoO3/MgO system

The solid-solid interactions in pure and MoO3-doped CuO/MgO system were investigated using TG, DTA and XRD. The composition of pure mixed solids were 0.1CuO/MgO, 0.2CuO/MgO and 0.3CuO/MgO and the concentrations of MoO3 were 2.5 and 5 mol%. These solids were prepared by wet impregnation of finely powdered basic magnesium carbonate with solutions containing calculated amounts of copper nitrate and ammonium molybdate followed by heating at 400-1000°C. The results revealed that ammonium molybdate doping of the system investigated enhanced the thermal decomposition of copper nitrate and magnesium hydroxide which decomposed at temperatures lower than those observed in case of the undoped mixed solids by 70 and 100°C, respectively. A portion of CuO present dissolved in the lattice of MgO forming CuO-MgO solid solution with subsequent limited increase in its lattice parameter. The other portion interacted readily with a portion of MoO 3 at temperatures starting from 400°C yielding CuMoO4 which remained stable up to 1000°C. The other portion of MoO3 interacted with MgO producing MgMoO4 at temperatures starting from 400°C and remained also stable at 1000°C. The diffraction peaks of Cu2MgO3 phase were detected in the diffractograms of pure and MoO3-doped 0.3CuO/MgO precalcined at 1000°C. The formation of this phase was accompanied by an endothermic peak at 930°C.

Phase relations in the MgMoO4-Mg3V2O8 system and crystal structure of Mg2.54V1.08Mo0.92O8

The phase relationships in the pseudobinary MgMoO4-Mg3V2O8 system have been determined by differential thermal analysis and X-ray diffraction analysis. The intermediate compound Mg2.5VMoO8 was found to exhibit a considerable solid solution Mg2.5+xV1+2xMo1-2xO8 (- 0.05 ≤ x ≤ 0.05) at 1100°C in air. Single crystals with composition of Mg2.54V1.08Mo0.92O8 were successfully grown from the Mg-V-Mo-Oxide flux. Mg2.54V1.08Mo0.92O8 crystallizes in the orthorhombic system, space group Pnma with a = 5.058(1) angstrom, b = 10.307(3) angstrom, c = 17.402(4) angstrom, Z = 6. The vanadium and molybdenum cations remain in their highest oxidation states and charge neutrality associated with the variation of the V/Mo atomic ratio is balanced by an increase or decrease in the number of magnesium cations in the crystal.

Investigation of the first-order phase transition in the Co 1-xMgxMoO4 solid solution and discussion of the associated thermochromic behavior

A series of compounds of Co1-xMgxMoO4 compositions has been prepared by a conventional ceramic route. The members of the whole solid solution exhibit a reversible first-order phase transition which was probed by using thermal expansion and low-temperature reflectivity techniques. Whereas the α → β transition temperature evolves linearly on warming from 435 to 200 °C with x going from 0 to 0.9, the β → α transition temperature variation falls down on cooling from -40 °C to -140 °C going from CoMoO4 to Co 0.1Mg0.9MoO4 with an asymptotic evolution. The phase transition temperatures have been explained on the basis of a crystal polarization effect under substitution of Mg for Co. Thus, from an applicative point of view, new thermochromic pigments with tunable transition temperatures are here proposed.

Cooperation between MoO3 and other metal oxides in selective oxidation of isobutene to methacrolein

A synergy is observed in the selective oxidation of isobutene to methacrolein when MoO3 is mixed mechanically with other metal oxides, either simple (Sb, Bi, Te) or binary (Cu-Sb, Bi-P, Zn-Fe, Ni-Mo, Co-Mo, Fe-Mo and Cu-Mo). In most cases, the effect can be explained by a remote control mechanism, namely the control of active sites of MoO3 through spillover oxygen emitted by the other phases. Roles of these admixed phases can be related to the ionicity of the bonds in their structure. The results strongly suggest that TeO2 behaves as an intermediate oxide, either as a donor when mixed with a strong acceptor or an acceptor when mixed with a strong donor.

Phase formation in the Ag2MoO4-MgMoO 4-Al2(MoO4)3 system

The subsolidus region of the Ag2MoO4-MgMoO 4-Al2(MoO4)3 ternary salt system has been studied by X-ray phase analysis. The formation of new compounds Ag 1-xMg1-xAl1+x(MoO4)3 (0 ≥ x ≥ 0.4) and AgMg3Al(MoO4)5 has been determined. The Ag1-xMg1-xAl1 + x(MoO 4)3 variable-composition phase is related to the NASICON type structure (space group R 3? c). AgMg3Al(MoO 4)5 is isostructural to sodium magnesium indium molybdate of the same formula unit and crystallizes in triclinic system (space group P 1?, Z = 2) with the following unit cell parameters: α = 9.295(7) ?, b = 17.619(2) ?, c = 6.8570(7) ?, α = 87.420(9)°, β = 101.109(9)°,. = 91.847(9)°. The compounds Ag 1 - xMg1 - xAl1 + x(MoO4) 3 and AgMg3Al(MoO4)5 are thermally stable up to 790 and 820°C, respectively. Pleiades Publishing, Ltd., 2010.

Spray pyrolysis synthesis and characterization of Mg1-xSrxMoO4 heterostructure with white light emission

Molybdates are inorganic materials with great potential in white phosphors application, being an alternative to traditional lighting sources. In this study, we report the synthesis and characterization of Mg1-xSrxMoO4 (x = 0, 0.25, 0.50, 0.75, and 1) powders with white light-emitting properties. Using X-ray diffraction, the formation of the monoclinic β-MgMoO4 phase was observed for x = 0 and the formation of the tetragonal scheelite phase of SrMoO4 was observed for x = 1. The formation of a heterostructure composed of both phases was found for compositions with x = 0.25, 0.50 and 0.75. Scanning and trasmission electron microscopy images showed that the Mg1-xSrxMoO4 particles exhibit a spherical morphology formed by several primary nanoparticles. Raman scattering spectroscopy enabled the accurate identification of the Raman modes for different compositions and their assignment to either the SrMoO4 or β-MgMoO4 modes. The bandgap energies were determined to fluctuate between 4.25 eV and 4.44 eV, being influenced by the degree of structural disorder. The photoluminescence emission spectra of the nanoparticles showed neutral- and cool-white emission with high-quality white light (CRI > 80%). The samples synthesized with x ≤ 0.50 are potential materials for the application in LED lamps (6500 K) and pure white-light sources (5500 K).
