Synthesis and characterization of tungsten carbide fine powders
(Ceramics International, 2015)
Fine tungsten carbide (WC) powder was prepared by solid state reaction between tungsten powder (W) and activated carbon cloth as a new carbon (C) source. The effect of temperature and time of heat treatment as well as the ...
Influence of heavy rare earth ions substitution on microstructure and magnetism of nanocrystalline magnetite
(Journal of Alloys and Compounds, 2009)
In this work we report results on the influence of heavy rare earth ions substitution on microstructure and magnetism of nanocrystalline magnetite. A series of Fe(2.85)RE(0.15)O(4) (RE = Gd, Dy, Ho, Tm and Yb) samples have ...
Core and shell structure of ytterbium sesquioxide nanoparticles
(Journal of Alloys and Compounds, 2010)
This paper reports results concerning the crystal structure of core and shell as well as microstructure of 25 nm-ytterbium sesquioxide (Yb(2)O(3)) nanoparticles synthesized using a unique method based on thermal decomposition ...
Effect of samarium addition and annealing on the properties of electrodeposited ceria thin films
(Thin Solid Films, 2011)
Samarium (Sm)-doped ceria (CeO2) (SDC) is a promising material for high temperature electrochemical devices. Our work demonstrates that thin SDC films can be prepared by a cost-effective electrodeposition method at a ...
Metal phosphate preparation using boron phosphate
(Materials Research Bulletin, 1997)
The solid-state conversion of basic magnesium, calcium, zinc, and lead compounds into corresponding crystalline phosphates by the BPO4 method has been investigated at 800 degrees C and 900 degrees C. Magnesium hydroxide ...
Porous acicular mullite obtained by controlled oxidation of waste molybdenum disilicide
(Materials Research Bulletin, 2014)
Porous acicular mullite was fabricated by using waste MoSi2 heating element and Al2O3. Careful calcination of the pulverized heating element led to the formation of a mixture of MoO3 and amorphous SiO2. This mixture was ...
Room-temperature ferromagnetism in Ni2+ doped TiO2 nanocrystals synthesized from nanotubular precursors
(Journal of Alloys and Compounds, 2014)
Hydrothermal synthetic route for synthesis of Ni2+ doped TiO2 nanocrystals showing room temperature ferromagnetism, using dispersion of titania nanotubes in the presence of Ni2+ ions at different pHs as precursors, is ...
Rapid crystallization of LiFePO4 particles by facile emulsion-mediated solvothermal synthesis
(Powder Technology, 2012)
Lithium iron phosphate powders were obtained by solvothermal treatments of quaternary emulsions Triton X-100/cyclohexane/n-hexanol/water at low temperature (180 degrees C), with or without stirring. Such synthesis conditions ...

(Journal of Alloys and Compounds, 2010)
The influence of the heat treatment on the structural and magnetic properties of the nanoparticle La0.7Ca0.3MnO3 compound has been studied. The starting single-phase sample was prepared by the glycine nitrate method without ...
Room temperature ferromagnetism in Cu2+ doped TiO2 nanocrystals: The impact of their size, shape and dopant concentration
(Elsevier, 2016)
Cu2+ doped TiO2 nanocrystals were synthesized using dispersions of titania nanotubes in the presence of Cu2+ ions as a precursors. The morphologies of nanotubular titania precursors and resulted Cu2+ doped TiO2 nanocrystals ...
