Description

Grinding of quartz was carried out in cetyl alcohol with two kinds of ball mill; the one was made of glass and the other was a rotating micro autoclave made of stainless steel. The results were compared with those of the ones without cetyl alcohol. The grinding conditions were from 2 houres to 64 hours at room temperature or high temperatures.<br>The effect of cetyl alcohol, temperature and grinding hour on the size distribution of quartz particles were investigated by sedimentation and scanning electron microscopy. It was found that the percentage under 15μ diameter of the treated quartz was larger than that of the non-treated quartz and the degree of coagulation of the treated particles was less than that of the non-treated one. The effect of temperature was not clearly seen.
