摘要

The preparation of fine MoSi_2 and MoSi_2-Si_3N_4 composite powders with specific surface area of 16-33 and 30-41 m~2/g respectively by evaporation of Si and Mo raw powder mixtures or coarse grained MoSi_2 in radio frequency inductively coupled nitrogen plasma flow was investigated. Specific surface area of obtained powders as well as content of MoSi_2 modifications, Si_3N_4 and extra phases Mo_5Si_3, Si depend on the raw powder feeding rate, the cooling gas flow rate and the composition of raw mixtures. The shape of the product particles was spherical for MoSi_2 and both spherical and whiskers for composites.
