Microstructure and phase constitution of the LaFe11.0Co0.8Si1.2 bulk and ribbon samples in as-cast state and after annealing, were studied. For both samples in as-cast state the dominant dendritic α-Fe phase was formed. Annealing of the samples resulted in homogenization of the microstructure and change of the phase constitution. The heat treatment resulted in development of almost single-phase of the NaZn13-type structure identified as LaFe11.0Co0.8Si1.2 with minor fraction of the α-Fe. The evolution of microstructure and phase constitution was verified by EDX analysis and Mössbauer spectroscopy.
