Abstract
The development of new sintering processes for ferroelectric perovskite-type oxynitrides is a crucial aspect of realizing practical applications of these materials. The present study examined the sintering of SrTaO2N with B2O3, a new additive. The addition of B2O3 was found to significantly lower the sintering temperature. In addition, observations by transmission electron microscopy showed that the B2O3 combined with SrO to form an amorphous structure that enhances the diffusion of elements during high-temperature sintering.
