  • Silicon Powder Properties Produced in a Planetary Ball

    Jan 15, 2020· 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

  • Synthesis of silicon nanocomposite for printable

    Renewed interest has been established in the preparation of silicon nanoparticles for electronic dev applications. In this , we report on the production of silicon powders using a simple ball mill and of silicon nanocomposite ink for screen-printable photovoltaic dev on a flexible substrate. Bulk single crystalline silicon was milled for 25 h in the ball mill.
