Abstract
The present paper reports on basic investigations of the controlled reaction sintering of MoSi2-based materials, including particle reinforced composites. It is shown, that certain amounts of preformed silicide phase in the powder mixtures are useful to achieve closed porosity by pressureless sintering of green compacts. This partial phase formation of alphaMoSi(2) can already take place during the mechanical treatment of the elemental powder mixtures by milling. In this context the role of volume changes linked with the phase formations are discussed.
