ABSTRACT

Since attempts were made to fabricate translucent polycrystalline alumina in the 1960s, considerable effort has been made to develop new transparent ceramics and improve their properties. The application of transparent ceramics nowadays is extensive, covering many areas. This review discusses the fundamentals of polycrystalline transparent ceramics, including a brief history, requirements for transparency, and important properties along with their feasible applications. In particular, details of γ-AlON are included as an example based on the constant anion lattice model and the authors’ results to help the readers’ understanding of transparent ceramics. Finally, the current research trend is explained to anticipate future research directions on transparent polycrystalline ceramics.

Key words: Transparent ceramics · Band gap · Birefringence · Optical properties · γ-AlON
