Section snippets Preparation of NiO/ZrO 2 composites. Commercial ZrO 2 (HW NANO, China) with particle size in the range 60–120 nm was milled at 400 rpm for 1, 5, 10, and 20 h using a planetary ball mill (Tencan XQM-0.4L, China). The phase and crystalline structure of the raw and milled ZrO 2 were characterized by X-ray diffraction …

Abstract Ball milling is a simple, fast, cost-effective green technology with enormous potential. One of the most interesting applications of this technology in the field of cellulose is the preparation and the chemical modification of cellulose nanocrystals and nanofibers.

This research is focus on the synthesis ZnO nanoparticles (ZnO NPs) with the difference calcined temperatures by Ball-milling technique that was characterized by employing technique including X-ray diffraction technique (XRD), Fourier Transform Infrared spectroscopy (FT-IR) and Raman spectroscopy.

The Fe doped ZnO nanoparticles were prepared using high-energy ball milling technique. The X-ray diffraction was utilized to study the effect of ball milling time on the crystalline structure. Field emission scanning electron microscopy was used to analyze the morphology of Fe doped ZnO.

In this work a computer model for the P4 planetary ball mill has been presented and the effect of plate and jar velocity investigated. Two extreme conditions have been simulated, namely (i) steel–steel interaction (no mill charge) and (ii) steel–fluorite, by changing friction coefficients.

In this study, tetragonal zirconia stabilised by 6 mol% MgO and 2 mol% Y2O3 (t-6MgO–2Y2O3–ZrO2) nanopowders with quasi-spherical morphology, uniform particle size, and narrower grain size ...

PZT ceramic powders were successfully prepared from the mixture of PbO, ZrO 2 and TiO 2 by mechanochemical synthesis in a planetary ball mill, under different milling conditions. Phase evolution during synthesis was monitored by X …

Obtained powders were milled by a planetary ball mill system with a rotation speed of 400 rpm, in air and Ar, where the milling time was 15, 30, 60 min. The crystal structure was characterized by powder X-ray diffraction (XRD) measurement using Cu K ɑ line ( λ = 1.54056 Å) at room temperature.
