Ball-To-Powder Weight Ratio, Silicon Carbide Powder, Atomic Force Microscope, Particle Analyzer , Scanning Electron MicroscopeAbstract
The present study was undertaken in order to elucidate the effect of the ball-to-powder weight ratio of Silicon Carbide powder in ball milling. The Silicon Carbide powder(SiC) was pulverized in a high energy ball mill with constant milling time of 8 hrs, constant milling speed of 300 rpm and varying the ball to powder ratio (BP ratio) of 20:1 and 40:1. The wet milling media was WC balls in Toluene (C6H6CH3). The powders of both samples were then characterized by Atomic Force Microscope (AFM), Particle Analyzer (Zeta sizer) and Scanning Electron Microscope (SEM). The average particle size was reduced to 432.7 nm with BP ratio 20:1 and 315.5nm by BP ratio 40:1 and there is no much change in roughness value.
