Investigations were made on factors influencing the corrosion of beryllium in high temperature water and steam. It was found that surface preparation appeared to have a significant effect on the corrosion behavior of beryllium. Etching of beryllium samples fabricated directly from powder resulted in increased attack. Cut samples showed a damaged surface layer which, unless removed by polishing, resulted in increased corrosion attack. It is judged that removal of 12 to 14 nails should be adequate. The re sults indicate that only materials fabricated directly from powder show significant corrosion resistance. Increasing the purity of beryllium resulted in decreased corrosron resistance. Coarse grained distilled and single crystal zone refined specimens underwent rapid catastrophic corrosion in water at 650 deg F. An apparatus was constructed to produce dilute alloys from high purity beryllium. Samples are melted in a BeO crucible, bottom poured and cast into a BeO mold. Three castings have been produced.
