Magnetic properties of trivalent Sm ions in SmxY2-xO3
(Journal of Alloys and Compounds, 2009)
Polycrystailline samples of the cubic SmxY2-xO3 solid solutions (x = 0 2, 0.5. 1 0, 1 4, 1.7 and 2.0) were prepared and analyzed by the XRD and magnetic susceptibility measurements. Random distribution of Sm3+ ions between ...
Preparation of Nanosized Non-Oxide Powders Using Diatomaceous Earth
(Science of Sintering, 2009)
In this paper the nanosized non-oxide powders were prepared by carbothermal reduction and subsequent nitridation of diatomaceous earth which is a waste product from coal exploitation. Our scope was to investigate the ...
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 ...
Crystal structure and magnetic properties of Y-2(Cu1-xMgx)(2)O-5 obtained by SHS method
(Journal of Alloys and Compounds, 2014)
The single-phase polycrystalline samples of Y-2(Cu1-xMgx)(2)O-5, x = 0.0, 0.05, 0.15 were successfully synthesized by a modified self-propagating high temperature synthesis. Effects of Mg+2 substitution for Cu+2 in ...
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 ...
