Phase studies of Nb-Si at 1500 deg C indicated two stable silicides alpha - Nb/sub 5/Si/sub 3/ and NbSi/sub 2/; Nb/sub 4/Si was not observed. It was found that alpha -Nb/sub 4/Si/sub 3/ is a special phase with variable composition and stability (NbSi/sub 0.58/ to NbSi/sub o.66/) at 1250 deg . The niobium bisilicide is a single phase (NbSi/sub 1.85/ to NbS/sub 2.20/ developed from alpha - Nb/sub 5/Sis/ub 3/ by replacement. (R.V.J.)
