Wet and dry milling methods have their advantages and disadvantages. Nanoparticles tend to agglomerate, making them difficult to disperse after grinding. Wet milling addresses this by encapsulating each nanoparticle in the liquid slurry. On the other hand, wet milling presents the possibility of introducing contaminants into the final product.

High-energy ball milling is a convenient way to produce nanosized powders. It is the most common method reported in the literature for the synthesis of intermetallic nanoparticles. Before a mechanical milling is started, powder (s) is loaded together with several heavy balls (steel or tungsten carbide) in a container.

High-energy ball milling and bead milling are frequently used methods to prepare sub-micron and nanomaterials. However, producing nanoparticles by high-energy ball milling or bead milling requires the particle size of raw materials below a few microns when the size of balls or beads is small and even up to 0.1 mm.

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, …

Two standard nanoparticle production systems are used: 'top-down' and 'bottom-up'. 'Top-down' refers to the physical crushing of source material using a milling system. 'Bottom-up' strategies build particles via chemical operations. Choosing a method should be determined by the chemical makeup and the features chosen for the nanoparticles.
