Abstract
The effect of rare earth (RE) elements, including Ce and La, on the sorption properties of Zr-Co getters was investigated in this work. The nanocrystalline Zr3Co intermetallic compound has been produced by mechanical alloying of the elemental powder. In all mechanical alloying experiments, the ball-to-powder weight ratio was 15:1. The phase evolution and microstructral change of powders during mechanical alloying and activation process were investigated by means of X-ray diffraction and scanning electron microscopy. The results showed that after an optimum mechanical alloying time of 16 h, the amorphous phase was produced. After the activation process, the studies revealed that Zr-Co-RE can be activated at lower temperature than Zr-Co getters and show better sorption properties.
