Abstract : The first production job undertaken by the Metallurgy Groups at Los Alamos was that of the specially-shaped high-density beryllium oxide bricks needed for the Water Boiler. Hot-pressing of BeO powder was found to be the most satisfactory method of obtaining intricately-shaped bricks of suitable density. This was accomplished by charging the powder into a graphite die, or mold, of suitable shape fitted with a punch, or plunger, of graphite. The die and contents were heated to about 1700 deg C by means of an induction coil connected to a high-frequency converter. During the heating period a pressure of 1000 psi was applied to the plunger, thus consolidating the semiplastic BeO powder into a dense coherent mass of the shape of the die.
