The evolution of a thin, amorphous neodymium hydroxide film to the C-type oxide—an HREM study

摘要: High-resolution electron microscopy accompanied by the collection of atomic-level images at video rates, followed frame-by-frame analysis record has been used to study decomposition Nd(OH)3 oxide. The reaction is observed go through intermediate NdOOH C-type Nd2O3. This sequence shown be in agreement with thermal and X-ray analyses. Analysis shows an amorphous phase crystallizing hydroxide which, turn, decomposes oxyhydroxide [-1 1 1] zone. From this a crystal sesquioxide [7 11] zone emerges minimal reconstruction except removal tilt boundary that existed oxyhydroxide. Efforts are being made propose mechanism for structure orientational observations resulting from loss water.
