Bulk ZrO2 polymorphs generally have an extremely high amorphization tolerance upon low energy ion and swift heavy ion irradiation in which ballistic interaction and ionization radiation dominate the ion–solid interaction, respectively. However, under very high-energy irradiation by 1.33 GeV U-238, nanocrystalline (40–50 nm) monoclinic ZrO2 can be amorphized. A computational simulation based on ...

Preliminary researches were carried out to study the effects of particle size on the wear behavior of a-C coating. The used nanoparticles are W (W-NPs), which have similar bulk hardness with ZrO2 (W: 7.5, ZrO2: 6.5, Mohs scale), but contain larger particles with the diameter of submicron and micron scale (Figure S1). The tribo-tests were performed under the same conditions with the ones used fo...

Un-doped and Cd-doped ZnZrO3/ZnO/ZrO2 nano composites (CDZZ-NCPs) (CD0-4) were synthesized by the hydrothermal method. The nano composites were characterized by various techniques such as Fourier Transform Infra-Red spectroscopy (FT-IR), X-ray Diffraction (XRD), Field Emission Scanning Electron Microscopy (FE-SEM) and Energy Dispersive X-Ray Analysis (EDS). The photocatalytic properties of CDZZ...

This paper reports the synthesis of CeO2/ZrO2 nanocomposite by wet chemical method using cationic surfactant (CTAB). The properties of the obtained nanocomposites were analysed by X-ray diffraction (XRD), Fourier transform infrared (FTIR), scanning electron microscoy (SEM), transmission electron microscopy (TEM), UV-Diffuse Reflectance Spectroscopy (UV-DRS) and photoluminescence (PL) spectrosco...

Zirconia (ZrO2) nanoparticles were synthesized by solution combustion using urea as an organic fuel. Brunauer-Emmett-Teller (BET), X-ray diffraction (XRD), thermal gravimetric analysis (TGA), transmission electron microscopy (TEM), UV-vis and Fourier transform infrared (FTIR) measurements were performed in order to characterize the catalyst. The calculated crystallite size of ZrO2, calculated w...

Zirconia doped Hydroxyapatite (HAP) nanocrystals [Ca10(PO4)6-x(ZrO2)x(OH)2]; (0 ≤ x ≤ 1 step 0.2) were synthesized using simple low cost facile method. The crystalline phases were examined by X-ray diffraction (XRD). The crystallinity percentage decreased with increasing zirconia content for the as-synthesized samples. The existence of zirconia as secondary phase on the grain boundaries; as obs...

In the present article a 45Mo-45Cu-10Al2O3 (wt%) nano-composite was produced by mechanical alloying, shaped cold pressing then hot at 950 °C. Our aim to investigate effect of different ball powder ratio (BPR) on particle size and shape, as well material composition. Investigations were done with XRD, SEM for pressed specimens Brinell hardness measurement. Lower BPR resulted in nano-sized crysta...
