摘要：

The sequence of antiferroelectric, ferrielectric and ferroelectric phases in the material AS573 (Hull, UK) has been investigated via conoscopy and selective reflection. Evidence was found to support the division of the phase previously labelled SmCgamma* into two ferrielectric subphases. A revised phase sequence for the material, based on this study, is presented.
