Spherical cadmium sulfide (CdS), with five kinds of particle size ranging from 31 nm to 117 nm were synthesized by microemulsion method. The phase composition and morphology of CdS were characterized by field emission scanning electron microscopy (FE-SEM) and X-ray diffraction (XRD), respectively...
We report the particle size dependent magnetic behaviour in the antiferromagnetic spinel CoRh2O4. The nanoparticles were obtained by mechanical milling of bulk material, prepared under sintering method. The XRD spectra show that the samples are retaining the spinel structure. The particle size decreases...
The intensity of the peaks decreased with increasing milling time in XRD analysis (Fig.1). This result is not consistent with the literature. Taşkıran et al. observed anorthite and free quartz peaks in their study. They reported that the peak intensity of the anorthite phase increased wit...
Primary crystallization of amorphous Al-Ni-Y alloys, giving a dispersion of nanometre-scale α-Al crystallites in an amorphous matrix, is studied using isothermal and non-isothermal DSC, XRD and TEM. Isothermal anneals followed by temperature scans reveal the influence of changing composition on th...
The reduced catalysts displayed uniform core sizes that ranged from 5.512.7nm as ascertained by TEM, which concurred well with XRD analysis. The BET results revealed the highly mesoporous nature of the silica shell, which contributes to the facile access of the reactant gas to the active sites ...
The phase structure and microstructure were studied using XRD,SEM and EDX. The result shows that varieties of main hard phase's particle sizes give rise to some transformation on phase structure; The existence of TiCsub results in much finer grains; The introduction of TiNnm brings up ...
Particle size of spraying powder is the key factor which affets the properties of tungsten carbide coating.Three types of WC-CoCr coatings with different WC particle size were sprayed by high velocity oxy-fuel(HVOF).The microstructure and properties were analyzed by SEM,XRD,micro-hardness tester...
The structure and properties of the nanocomposites were investigated by X-ray diffraction (XRD), Fourier transform infrared spectrum (FTIR), transmission ... QX Jia,YP Wu,YQ Wang,... - 《Composites Science & Technology》 被引量: 185发表: 2008年 Preparation and characterization of Y2O3 hollow ...
The phase composition and microstructure of the ceramic fillers were characterized by X-ray diffraction( XRD),transmission electron microscope( TEM)and scanning electron microscope( SEM). The effects of rutile particles volume fraction and size on the microwave dielectric properties of silicone rubber ...
