M. Licheron, SYNTHESIS OF (BA,K)(2)(PB,BI)O-4-DELTA, Materials science & engineering. B, Solid-state materials for advanced technology, 40(1), 1996, pp. 50-53
The synthesis of a new layered perovskite family is reported. The phas
e (Ba1-xKx)(2)(Pb1-yBiy)O-4 is the n = 2 member of Ruddlesden-Popper s
eries A(n+1)B(n)O(3n+1). The compounds have tetragonal symmetry and th
eir space group is I4/mmm. Single phasic polycrystalline samples were
obtained with K2NiF4-type structure for 0 less than or equal to x less
than or equal to 0.2 and 0 less than or equal to y less than or equal
to 0.3. The synthesis of these compounds was successful owing to a mo
dified sol-gel method.
