In this paper, many trouble points to design of Ta sintering furnace is discussed. Then the performance of manufactured furnace as a result of discussion, of sintered specimen decided by experiment is described.<BR>Discussing points are as follow, <BR>1 Selection of electrical heating source and arrengement of electrode.<BR>2 Chacking mechanism for pressed body of Ta powder.<BR>3 Compensating mechanism for thermal expansion and contraction of specinen.<BR>4 Heat insulating method. etc.<BR>Although it does not describe a final conclusion for correlation between a loss of sintered specimen, insulator, chack, electric source, it may be concluded Jhat heat insulation gave influence for elements described above is somewhat necessary.
