Abstract

The interaction among Lanthanum, Arsenic and Iron at high temperature in a pressure-tight reactor machined by H08 steel were studied by means of electron probe microanalysis, optical microscopy and X-ray diffraction to understand what compounds could be developed on the condition that the atomic ratio of La to As is 1:2. The result shows that the ternary compound La10Fe54As37 and the binary compound LaAs are the main interaction products at 1223 K. There are some Fe2As compounds developed meanwhile. Moreover, the eutectic compound Fe2As can be precipitated from ferrite with the temperature decreasing.
