Three samples of thorium powder as supplied by Horizons, Inc. of Cleveland, Ohio were compared. The powder was processed entirely without the use of protective atmospheres with the exception of the sintering which was performed in a tank argon atmosphere with a dew point of approximately -80°C and the hot-pressing which was carried out in vacuum. The equipment and procedures used for cold-pressing and sintering were identical to those used in the evaluation of Sylvania produced thorium powders. The hot-pressing was done with standard uranium hot-pressing equipment.
