Ultrasonic field induced chiral symmetry breaking of NaClO3 crystallization

It is found that chiral symmetry breaking can be achieved in NaClO3 crystallization under an ultrasonic field, with a large crystal enantiomeric excess (mean values > 0.967) in almost every crystallization, and complete chiral symmetry breaking can be realized by seed inducing under the ultrasonic field. The chirality propagating process through secondary nucleation originating from an initial nucleus or a seed can be directly observed, and this large enantiomeric excess can be explained through secondary nucleation induced by the cavitation of the ultrasonic field and a recycling process.
