Abstract
The metallographic and X-ray diffraction data are given for the new te rnary silicide U3MoSi2. This compound melts incongruently at approxima tely 1480 degrees C according to: U3MoSi2 --> U4MoSi3 + U2Mo3Si4 + L ( L = peritectic liquid). It was verified that molybdenum coexists with U3Si2 predominantly as U3MoSi2 Indexing of the powder pattern showed t hat U3MoSi2 has a simple cubic structure with lattice parameter a(0) = 10.69 +/- 0.01 Angstrom.
