Abstract
PURPOSE:To obtain a single crystal of molybdenum of high quality, free from residues of primary recrystallization particles and large size crystals, by processing the sintered products with hot rolls in the cross direction under specific conditions in the production of a molybdenum single crystal by processing and annealing sintered polycrystals formed from a molybdenum powder containing a crystal growth auxiliary. CONSTITUTION:A molybdenum powder containing a crystal growth auxiliary is formed and sintered to give sintered polycrystals. The sintered product is processed and annealed to give a single crystal of molybdenum. At this time, the processing of the sintered product is conducted by milling with hot rolls at 900-1,000 deg.C so that the cross direction rolling corresponds to 40-60% of the total rolling. The process according to the present invention gives a molybdenum single crystal of 5-15mm thickness. The sintered molybdenum product containing a crystal growth auxiliary is preferably produced by subjecting an auxiliary-containing molybdenum powder of F.S.S.S.0.8-2.0mu to CIP molding, sintered by heating up to 1,600 deg.C at an ascending rate of 100-300 deg.C/hr and at 1,600-1,750 deg.C.
