Description

The diffusion coefficient is one of the important parameters in evaluating a tritium permeation barrier. Using nuclear reaction analysis (NRA), we measured deuterium concentration in densified ceramics coating of Cr2O3-SiO2-CrPO4 and derived that the diffusion coefficient was 7.0x10-17 m2/s at 563 K.
