A fundamental possibility is demonstrated of using SHS-extrusion and SHS-compression methods, combining combustion and high-temperature deformation, for preparing compact materials and objects of silicide ceramics based on MoSi2. Formability of silicide ceramic by free SHS-compression is studied. The effect of holding time before high-temperature deformation, heating temperature, and metal binder content in an original charge workpiece, on the degree of synthesized material deformation is studied. Specimen macro- and microstructure, prepared by SHS-extrusion is provided, and the effect of high-temperature heating on specific electrical resistance is also studied.
