摘要：

Two new polymorphic erbium oxides have been found in small grains of nanophase ceramics by means of electron microscopy; one has a face-centered cubic (fcc) structure with lattice parameter a equals 0. 374 nm, the other has a monoclinic structure with a equals 0. 359 nm, b equals 0. 562 nm, c equals 0. 344 nm and beta equals 119. 3 degree . The formation of these oxides is also discussed.
