The trapping of neon was studied between 293 and 838K. The diffusion coefficients could be represented by Arrhenius equations:

α-tridymite (336-366K):     D(cm2/s) = 6.7 x 10-2 exp-[22500/RT]

β1-tridymite (418-474K):     D(cm2/s) = 9.9 x 10-1 exp-[24100/RT]

β2-tridymite (513-577K):     D(cm2/s) = 4.5 x 10-4 exp-[19100/RT]
