摘要：
The combustion synthesis of Mo5Si3 was carried out in a chemical furnace using 5Ti + 3Si mixtures as a chemical fuel. The synthesized single phase Mo5Si3 exhibited a spatial network microstructure and angular texture of crystals. The chemical composition and crystal morphology of intermediate phases suggest that the formation of Mo5Si3 occurs via dissolution of Mo in the Si melt followed by reactive diffusion in the supersaturated "liquid Si-Mo melt-solid Mo" system.
