Fig. 3 shows a typical TGDTA curve of the silica powder modified by ml of HTMS after ball milling for 24 h. The DTA curve showed two peaks at approximately 130 and 300 °C. The first endothermic peak corresponds to the loss of physically adsorbed and/or hydrogenbonded water from the silica powder [22].The second exothermic peak is ascribed to the thermal decomposition of hexyl groups [11].

In this study, silica nanoparticles (SiO2 NPs) were fabricated using a handmade ball mill as a novel, simple, rapid, costeffective, and green approach. The solgel method was also used to produce these NPs as a comparative method. The SiO2 NPs produced by both methods were characterized using highresolution transmission electron microscopy (HRTEM), dynamic light scattering (DLS), energy ...

The limit of inwater grinding of silica sand by a planetary ball mill, which gives a much higher grinding rate than tumbling ball mills, was investigated from the viewpoint of mechanical grinding conditions. The grinding limit and subsequent negative grinding were confirmed in the inwater grinding. To do this, the product fineness was evaluated on the basis of size analysis by the laser ...

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 ...
