• Random wave motion of characteristics and intensities measured in terms of frequency and normalized acceleration has been applied to vibratory compaction of UO<SUB>2</SUB> powder in a metal tube, and the results are compared with those obtained by other methods of vibration.<BR>Densification proceeds rather slowly but steadily with random wave compaction, which more-over does not appear to produce the particle segregation on the top layers of the UO<SUB>2</SUB> powder ex-perienced with sinusoidal and other forms of wave. Consequently, the densities obtained are con-sistently higher than by other methods of vibration at the same normalized acceleration level.<BR>Acceleration peaks, and not average values, appear to be the predominant factor determining the efficacy of vibration in particle compaction, while displacement peaks contribute little either to compaction or to particle segregation.
