studies on Rheolgical Behavir and Processing of Mosi2 Heating Element

Rheology and processing of MOSi2 for injection molding of cylindrical heating elements were studied MoSi2 production through colloidal processing requires a good estimtate of the critical powder volume content CPVC in the present research the powder mic consisted of a commercial MoSi2 powder and a binder composed of paraffin bee's wax and polyethylene viscosity of the mix was measured by an RVT viscometer at different powder contents and the CPVC was calculated to be~60-65% at 130 C and shear rated of 2.5 to 20/s it was concluded that CPVC depends on the speed shear rate and the temperatur of mixing it increased with these parameters the inject molded samples were sintered at 1300 C for 2 hours and their microstructures were observed by SEM and analyzed by EDS
