The formation of Ni 4 Nb 2 O 9 in system (A) is found. This high-temperature modiﬁcation of nickel niobate crystallizes in the rhombic system. Solid solutions (Sr 1-x Nix) 4 Nb 2 O 9 (0 ≤ x ≤ 0.25) and (Sr 1-x Nix) 6 Nb 2 O 11 (x = 0.17) are formed in the ternary system (B). — (PODKORYTOV, A. L.; PANTYUKHINA, M. I.; SHTIN, S.
