The purification procedures include ball milling, reacting with CO and hydrochloric acid, and washing with deionized water. Highpurity silica with a purity of >96 wt% is successfully separated from desert sand, river sand, and sea sand from different regions. The purification mechanism of silica from natural sand is revealed in this work as well.

Highly dispersed CuO/SiO2 catalysts were successfully synthesized by a green process of ball milling (BM) under solventfree and room temperature conditions. The structural evolution of CuO/SiO2 catalysts prepared by BM was elucidated by TGDSC, XRD, FTIR, and XPS characterizations. We found that the copper acetate precursor was dispersed over the layer of copper phyllosilicate which was ...

Several studies investigating the ballmilling of ductile facecentered cubic metals have reported a socalled insitu consolidation phenomenon where the milled powder is also consolidated during the milling process. Thus, instead of refined powders or agglomerated particles, the formation of spherical bulk particles of the milled material is reported using a combination of cryomilling and ...
