Abstract

In the course of studies of the Ca2Nb 07-NaNbO3 system, the existence of a family of phases of composition AnBnO3nt2 (where A represents Na and/or Ca, 4 ≤ n ≤ 6) was establishe and investigated by X-ray and electron microscopy methods (1 – 7). In the same area two other families have been studied ; the first one belongs to the same ternary system CaO-Nb2O5-Na2O with the formula : An+1BnO3n+1 (n = 4 and 5), the structure deriving directly from the K2NiF4 type, the other one being A2BnX3n+2 (A = Na, B = Nb and/ or W, X = 0 and/or F) (8–9).
