Abstract:Opacifier-free phase-separated opaque glaze is the research hotspot to date in the ceramic industry. In this review,definitions and mechanisms of phase-separated opaque glaze were summarized and current state of the art was introduced with emphasis laid on characteristics, performance, mechanisms of opacifying and the effects of different ingredients on opacifying behavir. At last, the main problems phase -separated opaque glaze confronting were analyzed and severa solutions were proposed.

Key words:opaque glaze; phase separation; current research situation; development trends
