MoSi2 is widely used for high-temperature heating elements owing to its low electric resistivity and good thermal conductivity. But, most of MoSi2 powders are not recycled. For recycling of waste MoSi2 materials , the heating element with bentonite and additives was fabricated using a vacuum extruder, which were then sintered at temperature of 1600℃. From the produced heating element, we investigated behavior of electric property according to the extrusion pressure, sintering temperature and sintering time. Electric property measured by electric discharge device. |
