Abstract
The structural properties and thermal decomposition kinetics of beryllium deuteride (BeD2) synthesized from isotope exchange method were investigated compared to beryllium hydride (BeH2) using infrared spectroscopy (IR) and thermogravimetric analysis (TG) techniques. The results indicate that infrared characteristic bands of BeD2 shift to lower frequencies compared to corresponding bands of BeH2; Infrared absorption intensities of BeD2 increase with temperature increasing; BeD2 possesses relatively higher activity energy and much larger pre exponential factor compared to that of BeH2, which leads to macroscopic less thermal stability.
