One of the most important problems concerning the Fe-Ni mineral tetrataenite in chondrites is to explain how the tetrataenite phase formed in space. The production of ordered structure of Fe-Ni grains using the gas evaporation technique is reported here. The structure can be explained as a structure of the Fe3Al type (DO3). The ordered structures of FeNi and FeNi3 were of the AuCuI (LI0) and Cu3Au (LI2) types, respectively. Differences in morphology due to crystal structure are shown.
