  • The effect of liquid additives on dry ultrafine grinding ...

    2001-1-15 · In this work, it is considered that the ultrafine grinding of quartz has been achieved by the addition of alcohol and glycol. The mean specific surface diameter of quartz is around 0.2 μm at the specific surface area of 11 000 m 2 /kg assuming ground quartz particles to be spheres. Fig. 3 shows the scanning electron micrographs of quartz obtained by the grinding with
