Abstract:

The pyrolysis of beryllium hydride was studied by following the rate of hydrogen evolution. The reaction is autocatalytic and appears to involve a process in which beryllium nuclei are formed at selective sites within the hydride followed by the subsequent growth of these nuclei. Various types of surface treatment produced essentially no effect upon the rate of pyrolysis, indicating that the nucleatcion and growth processes occur within the hydride particles rather than on their surface. The high temperature oxidation of BeH2 was studied using arc-imaging techniques. High-speed motion pictures of this reaction have indicated that at least a portion of the hydride undergoes very rapid pyrolysis followed by a slower reaction in which the Be is oxidized to BeO.
