Abstract

The crystal structure of Si3N4·Y2O3 prepared by a hot-press is examined in a 1 MV high-resolution electron microscope. The image contrast reveals that it is isostructural with one of the layered silicates, Akermanite, in accordance with the previous estimation by means of powder X-ray diffraction. The crystal growth from a glass phase is discussed briefly.
