Examination of bulk microstructures of lutetium doped erbium silicide (Er(0.9)Lu(0.1))(5)Si(4) (space group: Pnma) using scanning and transmission electron microscopy (SEM, TEM) reveals the existence of thin plates of a hexagonal phase (space group: P6(3)/mcm) where the stoichiometric ratio in moles between the rare earths and Si is 5 to 3, i. e the 5:3 phase. The orientation relationship between the matrix and the plates was determined as (m)approximate to parallel to[-1010](p). This observation adds credence to the assumption that all linear features noted in alloys of the rare-earth intermetallic family R(5)(Si(x)Ge(1-x))(4) are of the stoichiometric ratio 5:3 and possess a common orientation relationship with the parent 5:4 alloys.
