Résumé: The investigation in the system Bi2O3-SrO-TeO
2 reveals a new phase Bi2SrTeO7, crystallizing in a
cubic unit cell, space group Pa-3 [1] and lattice parameter a = 10.906 (7) Å.
The crystal structure was determined by means of the Rietveld method using the Full Prof [2]
program. Bi
3+
and Sr
2+
occupy the same site 24e, Te
6+
(1) and Te
6+
(2) occupy the sites 4a and 4b
respectively, the oxygen O
2-(1), O
2-(2) and O
2-(3 ) are located in the site 24e respectively.2014-01-01T00:00:00Z
