Abstract
A green compact (17) preheated to a predetermined temperature in a heating furnace (16) is inserted into a container comprising a press table (20) and a hollow cylinder (25), and molten glass (33) is then placed into the container. The green compact (17) is uniformly pressed by a press rod (29) through the molten glass (33). The molten glass (33) is cooled by a coolant flowing through channels (22) and (26) formed in the press table (20) and the cylinder (25), whereby a solidified shell (34) is formed at the outer peripheral portion of the mass of glass. Finally, the shell (34) is taken out from the container, and the molten portion of glass (33) is transferred into a ladle (31) through a grating (30), leaving the compressed sintered product on the grating (30).
