1871 B. Nason Wöhler's Hand-bk. Mineral Anal. 113 Fused with hydrate of potassa and saltpetre or chlorate of potassa, it forms ruthenite of potassa, KO, Ru O₃.

1892 Jrnl. Chem. Soc. 62 i. 282 Barium ruthenate, BaRuO₄, at 440° loses oxygen, and yields a ruthenite, BaRuO₃, different in properties from a mixture of barium monoxide and ruthenium dioxide.

1961 Proc. Indian Acad. Sci. A. 30 52/2 Lanthanum rhodite and Strontium ruthenite possess the perovskite structure.

1984 N. N. Greenwood & A. Earnshaw Chem. of Elements (1986) xxv. 1257 They include..the ‘ruthenites’, MⁱⁱRu^ivO₃.

2001 Materials Today July–Aug. 10/1 A ruthenite, La₄Ru₆O₁₉, exhibits very unusual properties—including non-Fermi liquid behavior.
