Zusammenfassung:The invention discloses a production method for sintering molybdenum blank in a low temperature activated mode. The production method can improve product quality, save energy and lower the fixed assets of production equipment. According to the technical scheme, the production method for sintering molybdenum blank in the low temperature activated mode is characterized by comprising the following steps that (1) forming is conducted, superfine molybdenum powder is filled into a molybdenum plate blank mold, the powder filling amount is 970 grams, filled powder includes a forming agent, and extrusion forming is conducted on an oil press of 250 tons or more than 250 tons; (2) presintering is carried out, formed molybdenum blank is placed into a first molybdenum wire furnace for presintering, and the presintering temperature is 1050 DEG C; (3) sintering is performed, pre-sintered molybdenum blank is placed into a second molybdenum wire furnace for sintering, and the sintering temperature is 1350 DEG C.
