Abstract

Attempts to synthesize ZnY₂O₄ are made via a solid-state reaction in a high-temperature X-ray powder diffraction chamber as well as analyzing Y₂O₃ sinter ceramics pressure infiltrated by ZnO in a scanning electron microscope using energy-dispersive X-ray spectroscopy and electron backscatter diffraction (EBSD). The microstructure of the sinter ceramic is composed of ZnO grains dispersed in an Y₂O₃ matrix. Superimposed EBSD patterns of Y₂O₃ are misindexed as ZnY₂O₄ during the EBSD scan. The literature concerning ZnY₂O₄ is critically discussed.
