Cast silicides of molybdenum, tungsten, and niobium by combustion synthesis
International Journal of Self-Propagating High-Temperature Synthesis - Tập 20 - Trang 100-106 - 2011
Tóm tắt
Cast silicides of molybdenum, tungsten, and niobium were prepared by combustion synthesis under nitrogen pressure from powder mixtures of respective metal oxides with Al and Si. Upon variation in green composition, cast MoSi2, WSi2, NbSi2, and their solid solutions with variable phase composition have been synthesized. NbSi2 was obtained by combustion in the presence of added heat-generating CaO2-Al powder mixture.
