Abstract:

A new high-pressure, high-temperature phase, Zn4Nb2O9, has been prepared at T = 1700degreesC, using a pressure of P = 9 GPa. An XRD study based on the Rietveld technique showed the structure to be corundum related (P (3) over bar c1, Z = 2) with the unit-cell parameters a = 5.1864(1) Angstrom, c = 14.1445(2) Angstrom. The structure consists of close-packed oxygen atoms, with 2/3 of the octahedral interstices occupied by zinc and niobium atoms. The space group was confirmed by micro diffraction and selected-area electron diffraction studies. (C) 2003 Editions scientifiques et medicales Elsevier SAS. All rights reserved.
