Crystal structure of Ca1−xSrxZr4(PO4)6 (0≤x≤1)

  • Werner Fischer (a1), Lorenz Singheiser (a1), Debabrata Basu (a2) and Amit Dasgupta (a2)

The crystal structure of several compounds of Ca1−xSrxZr4(PO4)6 ceramics has been investigated by X-ray powder diffraction at room temperature. All compounds form a solid solution with a unique unit cell. While the lattice parameter a of the hexagonal unit cell decreases of about 0.9% with increasing Sr content only slightly, it considerably elongates in c direction (2.8%). No structural transformation has been observed by high-temperature X-ray diffraction up to 1000 °C.
