Abstract

PURPOSE: To manufacture a long Mo pipe, by molding Mo powder into a pipe by using a mandrel, or by boring a hole through a material such as a round bar made of Mo to form a pipe.
CONSTITUTION: A hard rubber bag 2 is inserted into a cylindrical liner 1 made of iron or plastics, then a mandrel 3 made of Mo or iron is arranged at the center. Mo powder 2W5μm in particle diameter is filled in the space made between the rubber bag 2 and the mandrel 3 and is pressure molded by a hydrostatic press at 2ton/cm2 pressure. After the mandrel 3 is pulled out, the molded body is taken out of the bag 2. Or Mo powder is molded into a circular or square pillar, then the pillar is bored along the axis to form a molded cylindrical body. Said molded body 6, to which sliding powder is stuck, is layed on a sintering jig 5 of V boat shape and sintered at 1,700W1,900°C temp. for 5W7hr to manufacture long, thin Mo pipe.
