Abstract
HYDROXYL ions diffuse slowly in silicas and motion of these ions through a quartz network, or the formation of defects for this motion, involves breaking silicon-oxygen bonds which have a bond energy of more than 100 kcalories mol−1. Thus it is unlikely that White1 observed hydroxyl ion motion in quartz. His low activation energy of 13 kcalorie mol−1 is closer to that for the motion of monovalent cations2.
