N2 - This paper illustrates the capability, with the high resolution electron microscope and associated techniques, of characterizing a material with lateral resolution near the atomic level, temporal resolution at 1/30 s, and chemical analysis of volumes no more than 2 nm wide perpendicular to the electron beam. Pr0.5Tb0.5(OH)CO3, in the form of an amorphous colloidal sphere, is transformed through (Pr0.5Tb0.5O)2CO3 to the oxide, Pr0.5Tb0.5Ox. Chemical analysis through the various stages of decomposition establishes essentially random dispersal of the rare earths. Structural analysis of video frames at time intervals of a few 1/30 s permit progressive characterization of the material as it changes. This is relevant to the promulgation of mechanisms of solid state reactions at the atomic level.
