The structure of tetragonal NbOPO 4 has been studied from room temperature to 500ยฐยฐC by X-ray powder diffraction and to 327ยฐยฐC by neutron powder diffraction. Rietveld refinements were conducted on neutron data collected at 25, 100, 175, 200, 225, 275, and 327ยฐยฐC. A phase transition was found at abou
