The effect of careful control over metal and oxygen stoichiometry on the structures of various M[sub n+1]M[prime][sub n+1]O[sub 3n+5] phases (M = La and/or Sr, M[prime] = Ti and/or Nb) has been studied by transmission electron microscopy. In addition to the previously reported n = 3 and 4 layered phases and the n = [infinity] parent perovskite, ordered and disordered intergrowth structures comprising the n = 2, 3, 4, and [infinity] members have been characterized. The effects of in situ reduction in the electron microscope were studied. 18 refs., 8 figs.
