| wo methods, surface area and particle size determination, were used for investigation of particle size distributions generated during hydriding-dehydriding cycles of uranium. The initial pressure of each hydriding was in the range 156.518 to 219.845 kPa at room temperature. Dehydriding was carried out under vacuum conditions at a temperature between 573 to 800 K. Particle size determinations were carried out using 5 ;After 42 cycles the geometric mean particle diameters of uranium and hydrides were 0.377... |
