The room-temperature XRD pattern of polycrystalline Ca₃CoNb₂O₉ samples. The red solid cycles are our experimental data. The green solid line is the calculated XRD pattern for powder Ca₃CoNb₂O₉. The vertical lines indicate the reflection positions for Ca₃CoNb₂O₉. The difference curve is also presented as the black solid line.
