“…Among them, oxynitride perovskites have been characterized as both novel dielectric materials and harmless pigments. Recently, superior dielectric properties have been reported for SrTaO 2 N . Neutron diffraction confirmed the presence of short‐range O/N ordering involving a cis configuration in the TaO 4 N 2 octahedron from a nitrogen occupancy of half in its apical and one‐quarter of the equatorial sites in the octahedron.…”

“…Black colored conductive pellets were previously obtained when SrTaO 2 N was sintered with a SrCO 3 additive at high temperatures above 1300 °C under a 0.2 MPa N 2 atmosphere or when HIPped above 1200 °C at 196 MPa [5][6][7]. The TaO 0.9 impurity phase has also appeared in powder compacts annealed at 1100 °C in a silica tube under vacuum [6].…”

“…Sintering with hot isostatic pressing (HIPping) at 1400 °C under 196 MPa has also been applied to prepare highly densified SrTaO 2 N ceramics [7]. The color of the SrTaO 2 N ceramics also changed from brown to dark gray by HIPping and the original brown color was recovered by post-annealing in NH 3 .…”

“…Multinary oxynitride compounds are attracting much attention in applications such as white light emitting diodes (LEDs) [1,2], visible light driven photocatalysts [3,4], inorganic pigments [5,6] and dielectric materials [7][8][9][10][11][12]. The optical properties of the oxynitrides in the UV-vis range have been explained by the coexistence of nitride and oxide anions together because of the more covalent nature in nitride ion [13].…”
