Apr 29, 2005· The influence of ball‐milling methods on microstructure and mechanical properties of silicon nitride (Si 3 N 4) ceramics produced by pressureless sintering for a sintering additive from MgO–Al 2 O 3 –SiO 2 system was investigated. For planetary high‐energy ball milling, the mechanical properties of Si 3 N 4 ceramics were evidently improved and a homogeneous microstructure developed.
Thus, Si nanoparticles have been prepared from Si sawdust for LIBs, by means of plasma jet treatment 18, ultrasonic spraydraying 19, and high energy ball milling 20. They show high capacity (1000 ...
