Study on Interaction between Cerium and Arsenic
The interaction among Cerium, Arsenic and Iron at high temperature were studied by means of electron probe microanalysis, optical microscopy and X-ray diffraction. The result shows that the binary compound CeAs is the main interaction product when the atomic ratio of Ce to As is 1:2. The eutectic compound Fe2As can be precipitated from ferrite with the temperature decreasing, and the gray phase in bright field might be a ternary compound Ce12Fe57.5As41.
