The results indicated that the zircon phase is the major phase for the as-gained waste forms although containing 20mol% Eu3+. The alteration of 10-5~10-4 nm magnitude in the crystal cell parameters was measured (cf the standard XRD card of zircon). The equilibrium concentration of Eu3+ in HCI lixivium (pH=6.5) is less than 0.4μg/L.

Bonding structure and the change of chemical composition at the Cu/ceramic interface are investigated systematically with microanalysis. Furthermore, it is observed that copper bonding to Al〓O〓 ceramic is formed by chemical reaction between Cu〓O within the Cu-Cu〓O eutectic and Al〓O〓 at high temperature, CuAlO〓 as a reaction result is produced, mechanic join and physical osmose are not the main factor.

The results show that the technical parameters and the concentration of sodium molybdate have obvious effect on the composition of the alloy. The crystal grain size is from 6.2 to 12.7 nm and changes with current density, temperature and the pH value of the electrolyte.The crystalline growth of the alloy accords with the model of three-dimensional growth. The surface morphology is mainly determined by the rate competitions between the growing direction of vertical surface and the expanding direction along the surface towards circumambient. The results of the X-ray data show the presence of the multiphase containing solid solution and intermetallic compound in the deposits. The deposit phases alter from the FeNi and FeMo solid solution to the FeNi and MoNi4structure at 3 A/dm2. The deposits internal stress increases linearly with the decrease of the grain size. The lattice parameter of the deposits are slightly distorted
