Abstract
The invention of yttrium titanates (Y 2 Ti 2 O 7 ) with various exciting properties in electroceramics has created great attention among industrialists and researchers. Improving the materials of pyrochlore oxides with significant properties for future electronic devices became essential. The Y 2 Ti 2 O 7 is one such cubic pyrochlore at room temperature, having excellent dielectric and luminescence properties. This article comprehensively reviews the basics and state-of-the-art in developing Y 2 Ti 2 O 7 ceramics. This material is widely used for electronic devices: transducers, capacitors, optoelectronic components, and light modulators. This review focuses on the fabrication methods and crystal structure mechanisms for optimizing functional properties and current challenges. Moreover, the effect of doping elements of Y 2 Ti 2 O 7 -based ceramics is briefly discussed. Also, future perspectives are provided to spotlight new and trending research directions in this materials research.
