Small-Angle X-Ray Scattering of Quartz Near theαβTransition

Abstract
A series of experiments on the small-angle x-ray scattering of quartz over a temperature range centered on the αβ transition (573°C) showed no excess scattering during the phase transformation. This is taken to indicate that the previously reported "opalescence" (Yakovlev, Velichkina, and Mikheeva and Yakovlev and Velichkina) is probably not a critical phenomenon but arises from twinning inhomogeneities.
