摘要

The metallographic and X-ray diffraction data are given for the new ternary silicide U₃MoSi₂. This compound melts incongruently at approximately 1480°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 that U₃MoSi₂ has a simple cubic structure with lattice parameter a₀=10.69 ± 0.01 Å.
