Beryllium is considered to be basically an excellent material for moderators and reflectors in nuclear reactors, because of its nuclear properties and many of its other physical and mechanical properties. Although known for a long time, beryllium has been developed into an engineering material only during the last few years. This review covers the latest international information on beryllium both as a metal and as an oxide. It covers the occurrence of beryllium in nature, its extraction and fabrication in the metallic and oxidic form. The physical metallurgy is extensively discussed and special emphasis is given to the important problems of beryllium ductility. Based on the most recent research and development work, physical, mechanical, chemical, and nuclear properties of beryllium and beryllium oxide are described in detail. The behavior of these materials in neutron irradiation is briefly discussed. The application of beryllium or beryllium oxide as a matrix material for dispersion-type fuel elements is described. Examples are given for beryllium materials at present being used in nuclear reactors. Data on metallography are reported and a brief review is given of the health hazards in handiing beryllium and how to overcome them. The bibliography contains 99 of the most recent references to the beryllium literature. (auth)
