【 摘 要 】

A certain amount of rare earth element of cerium and low melting point of arsenic were closed in the barrel-shaped cylinder machined by H08 steel and heated to different temperatures for 1 h. XRD, optical microscope and SEM-EDS were used to study the interaction of the ternary system in the sample. It's shown that binary compound CeAs and Fe2As were the main products of the interaction. In the temperature range from 1173 K to 1273 K, the binary compound content of CeAs and Fe2As increased and then decreased with the increase of temperature. In addition, a schematic diagram of the corresponding mechanism of cerium iron and arsenic was given, and the results showed that CeAs and Fe2As were the basis for the formation of ternary compounds.
