The cation deficient complex oxides of (Ca/Sr)MoO4 - BiVO4 - Bi2Mo3O12 triple system are promising photocatalysts and pigments. Compounds with general formula of Ca1-1.5x-yBix+y?xMo1-yVyO4  and Sr1-1.5x-yBix+y?xMo1-yVyO4 were synthesized byconventio... see more

Novel BiVO4/CeO2 nanocomposites were synthesized by the hydrothermal method combined with the homogeneous precipitation method. The mole ratios of BiVO4:CeO2 were 0.4:0.6, 0.5:0.5, and 0.6:0.4. The obtained BiVO4/CeO2 nanocomposites were characterized by ... see more

X-ray diffraction phase analysis of samples performed on a DRON-6 diffractometer has shown that the processes of CaWO4 transition to WC and W2C had the highest probability in the temperature range of 1,173–1,473 K. The end-product CaWO4, thermally treated... see more

A series of strontium calcium tungstates Sr1-xCaxWO4 powders with (x = 0; 0.25; 0.5; 0.75 and 1.0) were prepared by solid-state reaction method and analyzed by X-ray diffraction (XRD). All these compositions possess a tetragonal scheelite structure with I... see more

The mineralization processes in the Peloritani Belt (Southern Sector of the Calabria- Peloritani Arc) prevalently developed during the Variscan orogenesis producing Pb, Zn, Fe, As, Sb, Cu, Ag, W, etc. polymetalliferous ore-bearing horizons. This paper foc... see more

Bi-Pb-Ag-Te oxides, sulfides and sulfosalts are relatively uncommon accessory minerals in the scheelite-bearing skarn of the La Falda Metamorphic Complex (Late Precambrian-Cambrian) of the Los Guindos mining group, Pampa de Olaen, Córdoba province, Argent... see more

The different rocks that host the tungsten-bearing quartz veins from central-eastern sector of the Famatina System (La Rioja, Argentina) are part of the crystalline basement of this unit. Petrographic and geochemical studies demonstrate that the emplaceme... see more

Single crystals of BaWO4, BaWO4: 0.5 at. % Ce; BaWO4: 1 at. % Ce; BaWO4: 0.5 at. % Ce, 1 at. % Na; and BaWO4: 1 at. % Ce, 2 at. % Na were grown from an inductively heated iridium crucible by the Czochralski method on a Malvern MSR4 puller. They were inves... see more
