Towards novel promising perovskite-type ferroelectric materials: High-pressure synthesis of rubidium niobate

Researchers have developed a novel high-pressure synthesis method for creating rubidium niobate (RbNbO₃), a perovskite-type ferroelectric material. This material is notable for its potential in capacitors due to its high dielectric properties. The study, led by Professor Ayako Yamamoto from the Shibaura Institute of Technology, involved synthesizing RbNbO₃ under conditions of 40,000 atmospheres and 1173 K. The resulting material exhibited enhanced dielectric polarization and underwent multiple phase transitions when subjected to a range of temperatures, making it a promising candidate for various electronic applications.
