KOH becomes embedded in the Si powder by the ball-milling process, rather than directly dissolved in water, so that (1) the heat of dissolution of KOH can be utilized to accelerate the hydrolysis of silicon and (2) the dissolution of KOH and sucrose helps disperse the Si powder in the water medium and the KOH also serves to dissolve any oxide formed on the Si surface in the form of soluble

For milling speed, since previous works usually used high speed ball milling which is more than 100 rpm, the best speed for low speed ball mill is unknown. Since higher speed results in higher collision between grinding balls and powder [ 7 ], the three highest speeds of the ball mill will be used which are 100 rpm, 95 rpm, and 90 rpm.

Mechanical milling is a promising route for production of submicron and nano sized silicon powders, but it is challenging to predict and control the product properties. In this study a metallurgical grade silicon quality was milled in a planetary ball mill and the properties of the powder were investigated as a function of grinding time, grinding bead size (20 mm, 2 mm, 0.25 mm) and rotational

The ball milling process is carried out for approximately 100–150 h to obtain uniform-sized fine powder. In high-energy ball milling, vacuum or a specific gaseous atmosphere is maintained inside the chamber. High-energy mills are classified into attrition ball mills, planetary ball mills, vibrating ball mills, and low-energy tumbling mills.
