  • Hydrogen Generation by Wet Grinding of Quartz Powders

       Hydrogen generation was investigated by grinding quartz powder in pH- and ionic strength-controlled liquid media. The effect of ionic strength on hydrogen generation was negligible while the decrease of generated hydrogen in the acidic pH region (>5.0) was observed. The mechanism of these mechanochemical reactions was discussed.

       It was found that mixtures of grinding media shapes can increase the breakage rate in a particular milling environment. But spherical balls remain the most efficient grinding media. Finally an optimal mixture made of grinding media of different shapes cheaper to manufacture can be used in the grinding process alternatively to 100 balls.

  • Kinetics of Radical Formation during the Mechanical

       The kinetics of radical formation during the mechanical activation of quartz by wet grinding or sonication was investigated using 2 2-diphenyl-1-picrylhydrazyl (DPPH) as a scavenger. The consumption of DPPH during the sonication of quartz in an ethanol suspension is a zeroth-order process. A linear relationship between the rate constant of the DPPH consumption and the quartz
