| Abstract: | Polycrystalline
samples of Ba(Zn1/3Nb1/3Ta1/3)O3
and Ba(Cd1/3Nb1/3Ta1/3)O3 have been
prepared by solid state reaction technique. Preliminary X-ray studies showed
the formation of single-phase compound. Zinc doped barium niobium tantalet had
a cubic unit cell and cadmium doped barium niobium tantalet had a tetragonal
structure. The d-values and
intensities for each reflection were computed using the lattice parameters,
which agree well with the observed values. The calculated and order line
intensities for both compounds decreased in the ordered which is expected from
the differences in the atomic scattering factor of B-ions, thus confirms the
1:1 degree of cation ordering. |
