ROOM TEMPERATURE FERROMAGNETISM IN Co-DOPED ZnO

·

Doping is performed by ball milling of 3 wt% of Co mixed with ZnO nanopowders (commercial) for durations of 28 h. X-ray diffraction data and high-resolution transmission electron microscopy (HRTEM) confirm the absence of metallic Co clusters or any other phase different from würtzite-type ZnO.

Cu-doped ZnO (Zn 1-x Cu x O) nano-ceramics were prepared by ball-milling of the CuO and ZnO powders. Up to 3 at% of Cu could be doped in ZnO via ball milling, beyond which Cu precipitates as CuO during calcination. The ac conductivity values decrease by Cu doping in ZnO, making it a better dielectric material.

Synthesis Approaches of Zinc Oxide Nanoparticles: The

Human's quest for innovation, finding solutions of problems, and upgrading the industrial yield with energy efficient and cost-effective materials has opened the avenues of nanotechnology. Among a variety of nanoparticles, zinc oxide nanoparticles (ZnO) have advantages because of the extraordinary physical and chemical properties. It is one of the cheap materials in cosmetic industry

Is Ball Milling An Innovative Technique For the Production

·

The oxide reduction reaction of ZnO with Al, which yields pure Zn as a product, cannot be induced using ball milling alone because of its low exothermicity. This study used a systematic combination of ball milling and annealing in order to induce the reaction.

Effect of the Milling Conditions on the Properties of ZnO

Apr 11, 2018· Abstract (Zn 0.9 Fe 0.1)O powders were produced with different ball to powder weight ratios (BPR) by ball milling of ZnO and Fe elemental powders.The BPR used were 15:1, 20:1, 25:1, and 30:1. The prepared samples were studied by x-ray diffraction (XRD), vibrating sample magnetometer (VSM), and Mössbauer spectroscopy (MS).

High-energy ball milling technique for ZnO nanoparticles

Apr 29, 2011· Abstract: Nanoparticles of zinc oxide (ZnO) are increasingly recognized for their utility in biological applications. In this study, the high-energy ball milling (HEBM) technique was used to produce nanoparticles of ZnO from its microcrystalline powder. Four samples were ball milled for 2, 10, 20, and 50 hours, respectively.

Correlation between microstructure and optical properties

Zinc oxide ZnO nanoparticles NPs in the size range 735 nm are synthesized by ball-milling technique, and microstructural and optical properties of the NPs are studied using varieties of techniques. Results from ball-milled NPs are compared with those of the commercially available ZnO nanopowder.

Efficient production of ZnO nanowires by a ball milling

·

Abstract ZnO powder was mechanically milled in a ball mill. This procedure was found to greatly increase its evaporation ability. The anomalous evaporation behaviour was caused by the disordered structure of the milled material and was not related to the increase in its surface area after milling.
