The main objective of this work was investigate the effect of ball milling on microcrystalline cellulose (MCC) structure. FTIR results shows there are no obvious different in the function groups of between neat and ball milling MCC. Both FTIR and WAXD analysis indicate that the crystalline of MCC samples are change with the ball milling time.

The structural transformation of polycrystalline Si induced by high energy ball milling has been studied. The structure and property characteristics of the milled powder have been investigated by xray diffraction, scanning electron microscopy, highresolution electron microscopy, differential scanning calorimetry, Raman scattering, and infrared absorption spectroscopy.

We present a study of multiferroic properties of YFeO3 synthesized by means of highenergy ball milling assisted by annealing at low temperature. Fe2O3 and Y2O3 powders were mixed in a stoichiometric ratio, milled for 5 h, pressed and annealed at temperature from 773 to 1073 K. Xray diffraction (XRD) analysis confirmed the formation of single ...

Cermet is an important new engineering material that not only maintains the excellent properties of ceramic materials, but also has the advantages of metal materials. In this paper, the encapsulated aluminaaluminum composite powder was prepared by ball milling and characterized, which laid a foundation for the development of high properties cermet materials.

The ball mill system consists of one turn disc (turn table) and two or four bowls. The turn disc rotates in one direction while the bowls rotate in the opposite direction. The centrifugal forces, created by the rotation of the bowl around its own axis together with the rotation of the turn disc, are applied to the powder mixture and milling ...

Highenergy vibratory ball milling (SuperMisuni, Nissin Giken Co. Ltd.) was employed, with a rotational speed of 710, where the milling atmosphere was ambient. The powders and zirconia balls (ϕ10 mm) were charged in a stainless steel vial (ϕ100 mm), where the balltopowder weight ratio was 18 : 1 (18 g balls per 1 g powder) and the ...

Ball milling pretreatment was found to be an efficient method to promote the catalytic conversion of lignocellulosic biomass to ethylene glycol (EG). After 3–6 h ball milling of Miscanthus at 450 rpm, the EG yield reached about 52%, which is comparable to the result of pure cellulose conversion. The reasons of the promotion effect were investigated by characterizing the structure of biomass ...
