Abstract:

Tungsten-molydiside WxMo1-xSi2 was synthesized by self-propagating high temperature synthesis. The SHS product with the initial composition of (0.5Mo+0.5W+2Si) contains 23.9% MoSi2, 40.89% WSi2 with remaining 9.11% Mo, 9.16% Si and 16.94%W. Lattice parameters of the MoSi2 and WSi2 determined by Rietvelt analysis were a=0.3206 nm, c=0.7841 nm and a=0.3212 nm, c=0.7822 nm, respectively.
