WebJun 4, 1998 · The crystal structure of α‐SiO 2 (low quartz) has been refined at 296, 78, and 13 K from time‐of‐flight neutron powder diffraction data. The major effect of temperature from 296 to 78 K is a nearly rigid body rotation of the SiO 4 tetrahedra. Below 78 K, tetrahedral rotation is substantially reduced giving rise to a much smaller thermal …
