Kinetic study on the grain growth of PuO(2) nanocrystals

Kinetic measurements on the grain growth of PuO(2) nano-crystals are presented. On the basis of isothermal XRD measurements at temperatures of 820 °C, 900 °C, 1000 °C, and 1100 °C the activation energy for the crystallite growth of PuO(2) nanopowder is determined as 351(5) kJ mol(−1) in the temperat...

description Kinetic measurements on the grain growth of PuO(2) nano-crystals are presented. On the basis of isothermal XRD measurements at temperatures of 820 °C, 900 °C, 1000 °C, and 1100 °C the activation energy for the crystallite growth of PuO(2) nanopowder is determined as 351(5) kJ mol(−1) in the temperature range from 820 to 1000 °C. Modelling shows that in this T range growth happens likely through surface diffusion.
