Abstract [en]

Black powder samples of the reduced oxotantalates Na1-xSrxTaO3 x = 0.2 and 0.3 were prepared via solid state reactions from appropriate amounts of NaTaO3, Sr5Ta4O15 and Ta (99.99%) in sealed tantalum ampoules at 1500degreesC. They crystallize in variants of the perovskite type structure (a(per)). According to structural refinements from neutron powder diffraction data Na0.8Sr0.2Ta03 crystallizes orthorhombic in the GdFeO3 type structure with unit cell parameters a approximate to root2 x a(per), b approximate to 2 x a(per), c approximate to root2 x a(per) and space group Prima. The structure of the more reduced phase Na0.7Sr0.3TaO3 is tetragonal with unit cell parameters a approximate to root2 x a(per), c approximate to 2 x a(per) and space group P4/mbm.
