摘要：

It is shown that the incommensurate (IC) phase near the alpha <-> beta transition point in quartz (SiO2) is an improper ferroelastic one and should be split into domains. The birefringence induced by such a ferroelastic phase is estimated, and it is shown that it can be as strong as is observed in experiments only if one accepts a new model for the IC transition in quartz.
